Symmetric *-polynomials on Cn
Journal Title: Карпатські математичні публікації - Year 2018, Vol 10, Issue 2
Abstract
∗-Polynomials are natural generalizations of usual polynomials between complex vector spa\-ces. A ∗-polynomial is a function between complex vector spaces X and Y, which is a sum of so-called (p,q)-polynomials.In turn, for nonnegative integers p and q, a (p,q)-polynomial is a function between X and Y, which is the restrictionto the diagonal of some mapping, acting from the Cartesian power Xp+q to Y, which is linear with respect to every of its first p arguments, antilinear with respect to every of its last q arguments and invariant with respect to permutations of its first p arguments and last q arguments separately. In this work we construct formulas for recovering of (p,q)-polynomial components of ∗-polynomials, acting between complex vector spaces X and Y, by the values of ∗-polynomials. We use these formulas for investigations of ∗-polynomials, acting from the n-dimensional complex vector space Cn to C, which are symmetric, that is, invariant with respect to permutations of coordinates of its argument. We show that every symmetric ∗-polynomial, acting from Cn to C, can be represented as an algebraic combination of some elementary'' symmetric ∗-polynomials. Results of the paper can be used for investigations of algebras, generated by symmetric ∗-polynomials, acting from Cn to C.

Some analytic properties of the Weyl function of a closed linear relation
Let L and L0, where L is an expansion of L0, be closed linear relations (multivalued operators) in a Hilbert space H. In terms of abstract boundary operators (i.e. in the form which in the case of differential operators...
A Worpitzky boundary theorem for branched continued fractions of the special form
For a branched continued fraction of a special form we propose the limit value set for the Worpitzky-like theorem when the element set of the branched continued fraction is replaced by its boundary.
On the structure of some minimax-antifinitary modules
Let R be a ring and G a group. An R-module A is said to be {\it minimax} if A includes a noetherian submodule B such that A/B is artinian. The author study a Zp∞G-module A such that A/CA(H) is minimax as a Zp∞-mod...
The inverse and derivative connecting problems for some Hypergeometric polynomials
Given two polynomial sets {Pn(x)}n≥0, and {Qn(x)}n≥0 such that deg(Pn(x))=deg(Qn(x))=n. The so-called connection problem between them asks to find coefficients αn,k in the expression Qn(x)=n∑k=0αn,kPk(x). The connecti...
A study on integer additive set-valuations of signed graphs
Let N0 denote the set of all non-negative integers and P(N0) be its power set. An integer additive set-labeling (IASL) of a graph G is an injective set-valued function f:V(G)→P(N0)∖{∅} such that the induced function f+:E...
