AbstractLet G be a finite transitive permutation group of degree n, with point stabilizer {H\neq 1} and permutation character π. For every positive integer t, we consider the generalized character {\psi_{t}=\rho_{G}-t(\pi-1_{G})}, where {\rho_{G}} is the regular character of G and {1_{G}} the 1-character. We give necessary and sufficient conditions on t (and G) which guarantee that {\psi_{t}} is a character of G. A necessary condition is that {t\leq\min\{n-1,\lvert H\rvert\}}, and it turns out that {\psi_{t}} is a character of G for {t=n-1} resp. {t=\lvert H\rvert} precisely when G is 2-transitive resp. a Frobenius group.

Regular Character

A low-mode geodynamo model is developed, controlled by 6-jet convection in the core of the Earth. The model contains only four modes, representing the fields of temperature, velocity, and two fields of magnetic induction. The magnetic modes was chosen by combining eight magnetic modes of free decay. There are two noise components in the model. In the model, stable regimes of generation of a magnetic field with reversals having a regular character were obtained. These reversals do not cause changes in the convection structure.

High Coherence

The diagnostic facilities of the cross power spectrum and the coherence function have been employed to enhance the identification of not only the inception of cavitation, but also its level. Two piezoelectric pressure transducers placed in the downstream chamber of a model spool valve undergoing various levels of cavitation allowed for the use of both functions—the phase angle of the complex cross spectrum and the dimensionless coherence function—to sense clearly the difference between noise levels associated with a noncavitating jet from those once cavitation inception is attained. The cavitation noise within the chamber exhibited quite a regular character in terms of the phase difference between instruments for limited cavitation. Varying cavitation levels clearly illustrated the effect of bubble size on the attendant frequency range for which there was an extremely high coherence or nearly perfect causality.

The analytical solution of an approximate (truncated) equation for the vector of a rigid body finite rotation has made it possible to solve the problem of determining the quaternion of orientation of a rigid body for an arbitrary angular velocity and small angle of rotation of a rigid body with the help of quadratures. Proceeding from this solution, the following approach to the construction of the new analytical algorithm for computation of a rigid body orientation with the use of strapdown INS is proposed: 1) By the set components of the angular velocity of a rigid body on the basis of mutually — unambiguous changes of the variables at each time point, a new angular velocity of a rigid body is calculated; 2) Using the new angular velocity and the initial position of a rigid body, with the help of the quadratures we find the exact solution of an approximate linear equation for the vector of a rigid body finite rotation with a zero initial condition; 3) The value of the quaternion orientation of a rigid body (strapdown INS) is determined by the vector of finite rotation. During construction of the algorithm for strapdown INS orientation at each subsequent step the change of the variables takes into account the previous step of the algorithm in such a way that each time the initial value of the vector of finite rotation of a rigid body will be equal to zero. Since the proposed algorithm for the analytical solution of the approximate linear equation for the vector of finite rotation is exact, it has a regular character for all angular motions of a rigid body).

AbstractThe higher Lie characters of the symmetric group Sn arise from the Poincaré-Birkhoff-Witt basis of the free associative algebra. They are indexed by the partitions of n and sum up to the regular character of Sn. A combinatorial description of the multiplicities of their irreducible components is given. As a special case the Kraśkiewicz-Weyman result on the multiplicities of the classical Lie character is obtained.

Critical analysis of concepts and terminology of geopolitics was made. Paradigm of scientific analysis of global geopolitical processes was proved. The basic modern global political trends were represented. A regularity formation and change of civilizations-cultures were grounded. Significant relationships and dependencies in the geopolitical system in the world were defined. The regular character of the convergence of the territorial organization of political and ethnic areas of the modern world was exposed. Incorrect methodological approaches to the analysis of the geopolitical situation in Ukraine were allocated. Key words: geopolitics, objective geopolitical analysis, methodology of geopolitics, conceptual foundations of geopolitics, geopolitical trends.

PurposeThe authors study the interdisciplinary relation between graph and algebraic structure ring defining a new graph, namely “non-essential sum graph”. The nonessential sum graph, denoted by NES(R), of a commutative ring R with unity is an undirected graph whose vertex set is the collection of all nonessential ideals of R and any two vertices are adjacent if and only if their sum is also a nonessential ideal of R.Design/methodology/approachThe method is theoretical.FindingsThe authors obtain some properties of NES(R) related with connectedness, diameter, girth, completeness, cut vertex, r-partition and regular character. The clique number, independence number and domination number of NES(R) are also found.Originality/valueThe paper is original.

The journalist is a regular character in Spanish films, and analysing this role is fundamental in learning more about the profession. The aim of this research is to identify the profile of the journalist in cinema from 1990 to 2010, two decades of drastic changes in the modes of communication in our country. In its empirical phase, one of the fundamental contributions can be found in the recovery of Morphology of the Folktale (1928), by Russian Folklorist-Scholar Vladimir Propp, which can be used to establish the characteristics of the reporter from a structuralist point of view. In this book, the conclusion reached is that the heroes are those in charge of serious journalism, whereas the villains, mainly women, are the stars of the television ‘boom’ with a predominance of morbidity and deceit on the small screen.

Initial Motion

The hydrodynamics laws describe well the laminar motion of a continuous medium where the particle trajectories and streamlines have fully defined regular character. However, random deviations, or “disturbances”, significantly change the nature of the initial motion, and cause a transition to a new or constant movement, or to some chaotic. This chapter studies forms of motion of a viscous fluid that is very common in the atmosphere and is called the turbulent motion.

AbstractLet G be a reductive p-adic group. Given a compact-mod-center maximal torus S⊂G and sufficiently regular character χ of S, one can define, following Adler, Yu and others, a supercuspidal representation π(S,χ) of G. For S unramified, we determine when π(S,χ) is generic, and which generic characters it contains.
