Extension of differentiable local mappings on linear topological spaces
Genrich Belitskii, Victoria Rayskin
Usually, for extension of local maps, one uses multiplication by so called bump functions. However, majority of infinite-dimensional linear topological spaces do not have smooth bu…

On a conjecture of the paper Differentiability of the Conjugacy in the Hartman-Grobman Theorem
Genrich Belitskii, Victoria Rayskin
In this note we show that for the construction of differentiable conjugation, the assumption of the existence of smooth bump function is not necessary, and consequently the corresp…

A connection between tests for absolute convergence of infinite series, or how to be fair
Victoria Rayskin
The Ratio Test and the Root Test for absolute convergence/divergence of series of numbers are frequently discussed and proved independently in Calculus cou…
