In the present article we study the periodic structure of a class of maps on the n-dimensional torus such that the eigenvalues of the induced map on the first homology are dilations of roots of unity. This family of maps shares some properties with t

We provide a general formula and give an explicit expression of the Lefschetz zeta function for any quasi-unipotent map on the space X = S l × ⋯ × ︸ n − times S l , with l > 1 . Among the quasi-unipotent maps are Morse–Smale diffeomorphisms

We provide a general formula and give an explicit expression of the Lefschetz zeta function for any quasi-unipotent map on the n -dimensional torus. The Lefschetz zeta function is used to characterize the minimal set of Lefschetz periods for Morse–

We prove the following Cantor–Bernstein type theorem, which applies well to the class of symmetric sequence spaces studied earlier by Altshuler, Casazza, and Lin: Let X and Y be Banach spaces having symmetric bases (xn) and (yn), respectively. If e

We prove the following general result: Let ( x n ) be a boundedly complete symmetric basis for a Banach space X. Then, for every symmetric basic sequence in X, we have the following alternatives: (a) it is equivalent to a basic sequence generated by

For two Banach spaces X and Y , we write dim'(X) = dim'(Y ) if X embeds into Y and vice versa; then we say that X and Y have the same linear dimension. In this paper, we consider classes of Banach spaces with symmetric bases. We say that such a class

Let $X_a$ denote the order continuous part of a Banach lattice $X$, and let $\Gamma$ be an uncountable set. We extend Drewnowski's theorem on the comparison of linear dimensions between Banach spaces having uncountable symmetric bases to a~class of d

We describe an algorithm to determine whether or not a given system of congruences is satisfied by Cullen numbers. We use this algorithm to prove that there are infinitely many Cullen numbers which are both Riesel and Sierpinski. (Such numbers should
