In this paper I give a completed topological characterization of Stein manifolds of complex dimension >2. Another paper (see [E14]) is devoted to new topogical obstructions for the existence of a Stein complex structure on real manifolds of dimension 4. Main results of the paper have been announced in [E13].

We give some examples of Stein manifolds which are not diffeomorphic, as oriented manifolds, to any smooth affine algebraic variety. Some of these examples are in complex dimension 2.

The Relationship

Abstract We develop the relationship between quaternionic hyperbolic geometry and arithmetic counting or equidistribution applications, that arises from the action of arithmetic groups on quaternionic hyperbolic spaces, especially in dimension 2. We prove a Mertens counting formula for the rational points over a definite quaternion algebra A over ${\mathbb{Q}}$ in the light cone of quaternionic Hermitian forms, as well as a Neville equidistribution theorem of the set of rational points over A in quaternionic Heisenberg groups.

Abstract This is a general study of twisted Calabi–Yau algebras that are $\mathbb {N}$ -graded and locally finite-dimensional, with the following major results. We prove that a locally finite graded algebra is twisted Calabi–Yau if and only if it is separable modulo its graded radical and satisfies one of several suitable generalizations of the Artin–Schelter regularity property, adapted from the work of Martinez-Villa as well as Minamoto and Mori. We characterize twisted Calabi–Yau algebras of dimension 0 as separable k-algebras, and we similarly characterize graded twisted Calabi–Yau algebras of dimension 1 as tensor algebras of certain invertible bimodules over separable algebras. Finally, we prove that a graded twisted Calabi–Yau algebra of dimension 2 is noetherian if and only if it has finite GK dimension.

Who gets what in portfolio allocation, and how does it matter to coalition partners’ legislative support in presidential systems? I propose that portfolios are not all alike, and that their allocation as well as the support for the president's agenda depends on the particular distribution of assets within the executive. The portfolio share allocated to coalition parties is weighted by a measure of importance based on the assets controlled by the ministry in question, such as policies, offices, and budgets. Once the weighted allocation of ministries has been identified, the results show that: 1) the president concentrates the most important ministries in their own party, mainly considering the policy dimension; 2) the positive relationship between portfolio allocation and legislative support remains, with the importance of specific dimensions being considered; and, 3) coalition partners do not respond differently in terms of legislative support in light of the different assets’ distribution within the portfolio allocation.
