On the theme of Le page
Journal Title: Математичні Студії - Year 2017, Vol 48, Issue 1
Abstract
Some Le Page's commutativity criteria (in complex Banach algebras) are considered. We try to reconstruct a brief history of their evolution. Our recent results, in the real case, are also presented. These propositions are referred in the general framework of not-normalized topological algebras.

Lattices of coarse structures
We consider the lattice of coarse structures on a set X and study metrizable, locally finite and cellular coarse structures on X from the lattice point of view.
Convergence of some branched continued fractions with independent variables
In this paper, we investigate a convergence of associated multidimensional fractions and multidimensional \emph{J}-fractions with independent variables that are closely related to each other; the coefficients of its part...
On the l-index boundedness of some composition of functions
It is suggested that for an entire function f the function F(z)=f(q(1−z)n), n∈N, is of bounded l-index with l(|z|)=β(1−|z|)n+1, β>1, if and only if f is of bounded index.
Problem of determining of minor coefficient and right-hand side function in semilinear ultraparabolic equation
The problem of determining of the right-hand side function and the time depended minor coefficient in semilinear ultraparabolic equation from the initial, boundary and overdetermination conditions, is considered in this...
Existence of solitary traveling waves in Fermi-Pasta-Ulam system on 2D–lattice
The article deals with the Fermi–Pasta–Ulam system that describes an infinite system of particles on 2D–lattice. The main result concerns the existence of solitary traveling wave solutions. By means of critical point the...
