Separating polynomials and uniform analytical and separating functions

Abstract

We present basic results of the theory of separating polynomials and uniformly analytic and separating functions on separable real Banach spaces. We consider basic properties of separating polynomials and uniformly analytic and separating functions. We indicate a relation between weak polynomial topology and norm topology of a space, provided it admits a separating polynomial. We present sufficient conditions for the existence of analytic and uniformly separating functions. We investigate a composition of an uniformly analytic and separating function and a linear mapping.

A family $\mathcal{A}$ of non-empty subsets of a set $X$ is called an {\em upfamily} if for each set $A\in\mathcal{A}$ any set $B\supset A$ belongs to $\mathcal{A}$. An upfamily $\mathcal L$ of subsets of $X$ is said to...

Let A and B be n-by-n matrices over a field. The study of the relationship between the products of matrices AB and BA has a long history. It is well-known that AB and BA have equal characteristic polynomials (and, theref...
