AbstractWe study products of irreducible theta divisors from two points of view. On the one hand, we characterize them as normal subvarieties of abelian varieties such that a desingularization has holomorphic Euler characteristic $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}1$. On the other hand, we identify them up to birational equivalence among all varieties of maximal Albanese dimension. We also describe the structure of varieties $X$ of maximal Albanese dimension, with holomorphic Euler characteristic $1$ and irregularity $2\dim X-1$.

The study To Publish, Make Known and Sell is based on verified existence of competition tensions between the 15th century typographers/publishers, related to the absence of functional regulatory tools of book production of the incunabula period. The increase in the number of book-printers within the relatively narrow geographical area, disregard of publishers’ privileges, the emergence of pirated reprints, as well as insufficient self-promotion on the book market through introducing novelties had concentrated typographers’ attention on devising new tools of securing their triumph in publisher’s competition – the so called book advertisements. The author has analysed 44 promotional posters of the incunabula period from several points of view and attempted to identify their design elements, which on the one hand showed signs of certain standardization, while on the other hand they were subject to personal creativity of their creator. She gives detailed overview of the circumstances of the origin, typographic design and contents of book advertisements of several kinds within the context of promoting either the existing or planned editions, of one edition or a group of books; specifically focusing on the unique types of advertising. In conclusion, the author cites the circumstances of the extinction of book advertisements related to the rise of the new promotional tool – booksellers’ catalogue and submits a bibliography of the book advertisements dating from the 15th century.

The article explores the typological principles and genesis of narrative thinking of Thomas Bernhard (1931-1989). It reveals the paradoxical nature of his writing, which combines, on the one hand, archetypal structures, implied ‘genre memory’, and on the other hand, a unique, innovative style. Bernhard’s constructive principle is repetition, which allows the embodiment of the idea of «eternal return» (Eliade) throughout the poetical structure, whether it is a sacred event of a myth or an «obsessive repetition» (Freud) of the traumatic memories of the protagonist or the narrator. The fragmented world is under constant reorganizing with the help of Bernhard’s polyphonic writing, which finds itself mostly in the imitation of the non-figurative, purely expressive, self-referential «art of fugue» (Bach), oriented to the cyclic, rather than linear-historical concept of time. In contrast to the literary interpretation of the «polyphonic novel» (Bakhtin) with its coexistence of multiple points of view, our attention is shifted to the musicological interpretation of the fugue’s polyphony as the embodied idea of the continuity of time, the closeness and infinity of the divine universe.

AbstractThis paper gives a new characterization of the dimension of a normal Hausdorff space, which joins together the Eilenberg-Otto characterization and the characterization by finite coverings. The link is furnished by the notion of a system of faces of a certain type (N1,..., NK), where N1,..., NK, K are natural numbers. It is shown that a space X contains a system of faces of type (N1,..., NK) if and only if dim(X) ≥ N1 + … + NK. The two limit cases of the theorem, namely Nk = 1 for 1 ≤ k ≤ K on the one hand, and K = 1 on the other hand, give the two known results mentioned above.

The purpose of this paper is to relate two notions of Sobolev and BV spaces into metric spaces, due to Korevaar and Schoen on the one hand, and Jost on the other hand. We prove that these two notions coincide and define the same p-energies. We review also other definitions, due to Ambrosio (for BV maps into metric spaces), Reshetnyak and finally to the notion of Newtonian–Sobolev spaces. These last approaches define the same Sobolev (or BV) spaces, but with a different energy, which does not extend the standard Dirichlet energy. We also prove a characterization of Sobolev spaces in the spirit of Bourgain, Brezis and Mironescu in terms of "limit" of the space Ws,p as s → 1, 0 < s < 1, and finally following the approach proposed by Nguyen. We also establish the [Formula: see text] regularity of traces of maps in Ws,p (0 < s ≤ 1 < sp).

In Anarchy, State, and Utopia, Robert Nozick contrasts entitlement theories of justice and “traditional” theories such as Rawls', utilitarianism or egalitarianism, and advocates the former against the latter. What exactly is an entitlement theory (or conception or principle) of justice? Nozick's book offers two distinct characterizations. On the one hand, he explicitly describes “the general outlines of the entitlement theory” as maintaining “that the holdings of a person are just if he is entitled to them by the principles of justice in acquisition and transfer, or by the principle of rectification of injustice (as specified by the first two principles of just acquisition and transfer)” (Nozick, 1974, p. 153). On the other hand, his famous “Wilt Chamberlain” argument against alternative theories is first said to apply to (all) “non-entitlement conceptions” (p. 160), and later to any “end-state principle or distributional patterned principle of justice” (p. 163) — which amounts to an implicit characterization of an entitlement conception (theory, principle) as a conception of justice which is neither end-state nor patterned.

When writing Macbeth, Shakespeare faced a moral and aesthetic challenge. On the one hand, he had drawn the story of Macbeth from Holinshed's Chronicles, in which Banquo is depicted as an accomplice in the murder of King Duncan. On the other hand Banquo was believed to be the ancestor of King James, Shakespeare’s patron. Shakespeare had to write a play that at once pleased King James, remained true to the spirit of history, and could be a popular hit in the commercial world of Jacobean theatre, all seemingly contradictory ends because of the problem with the character of Banquo. So Shakespeare characterizes him in a different manner from his sources. The new characterization served a number of purposes. The most important reason for the alternation was to please King James, the alleged descendant of Banquo. Other than that, there is the dramatic purpose of creating a foil character for Macbeth, who can highlight Macbeth's characteristics. The presence of a noble Banquo also shows that human being can resist evil, as does Banquo. These points have been emphasized in many writings on Macbeth, which mean that Shakespeare's Banquo is an innocent man, a seemingly deviation from history. The present paper, however, tries to examine Shakespeare's complex characterization of Banquo which must meet those seemingly contradicting ends, a characterization far more ambivalent and artful than simple political affiliations might suggest. It will be shown that Shakespeare's Banquo not only is not simply an innocent man he seems to be at the first reading, but he could be as murderous as Macbeth himself. The only difference between the two is that one acts sooner than the other.

This introduction offers a summary of the antecedents, goals, and prospects of the present volume. On the one hand, it emphasizes the important role of this collection of papers. It’s the first attempt to provide a global characterization of the syntactic variation of Spanish dialects. This is a very rich, but largely unexplored, area of inquiry, a situation that is probably due to a combination of various factors: lack of theoretical tools, interest in more easily observable (lexical, phonetic, or morphological) differences, etc. On the other hand, it introduces chapters that show varying and complementary formal approaches to the study of the syntactic phenomena of both American Spanish and European Spanish dialects.

Resum: Aquest article analitza la polèmica generada en la premsa valenciana l’any 1961 entre Joan Fuster i Josep M. Bayarri, arran del cinquantenari de la mort de Teodor Llorente. Mentre que Fuster reclama un debat intel·lectual al voltant del líder de la Renaixença valenciana i, de retop, dels referents propis, Bayarri en té prou amb commemoracions i celebracions, com misses, lectures de poemes o articles de diari. Aquest enfrontament dialèctic amaga dues maneres totalment oposades d’entendre el valencianisme de postguerra: d’una banda, un valencianisme que proposa l’autocrítica i la reflexió; d’una altra, un valencianisme o «regionalisme» irracional, de caire sentimentalista i antiintel·lectual. L’article analitza, doncs, el posicionament i l’abast de la defensa de Llorente per part d’aquests dos autors.Paraules clau: Teodor Llorente, Joan Fuster, Josep M. Bayarri, valencianisme, postguerra..Abstract: This paper analyses the controversy that Joan Fuster and Josep M. Bayarri create on the Valencian press in 1961, as a result of the fifty years after Teodor Llorente’s death. Whereas Fuster demands an intellectual discussion about the leader of the Renaixença in Valencia and the Valencian writers, Bayarri settles for commemorations and celebrations, masses, poetry readings or journal articles about him. This dialectic confrontation conceals two totally opposed ways of understanding the Valencianism of the postwar period. On the one hand, there is a Valencianism that proposes a self-criticism and a reflection; on the other hand, we find a Valencianism or an irrational «regionalism» that is sentimentalist and anti-intellectual. Therefore, this essay analyses the points of view about Llorente made by these two authors.Keywords: Teodor Llorente, Joan Fuster, Josep M. Bayarri, Valencianism, postwar period.

A few remarks on the contrastive analysis of styleThe phenomenon of style, analysed from different points of view, has been presented in this article. On the one hand, connections between stylistics and pragmalinguistics with the psychological profile of the sender have been indicated. Janusz Reykowski’s distinction of the five levels of centralisation, included in his publications, has turned out to be most useful in the pragmalinguistic analysis while describing the locutionary act, including the stylistic phenomena. On the other hand, though, a question about thepossibility and limits of the reflection of style in translation has been asked, using the text example in a German-Polish pair, and working out the criteria of evaluation. In the conclusion of the article the author is postulating the formation of a German-Polish contrastive stylistics.
