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.

The nonlocal problem for the differential-operator equation of the even order with the involution
In this paper, the problem with boundary non-self-adjoint conditions for differential-operator equations of the order $2n$ with involution is studied. Spectral properties of operator of the problem is investigated. By a...
On meromorphically starlike functions of order $\alpha$ and type $\beta$, which satisfy Shah's differential equation
According to M.L. Mogra, T.R. Reddy and O.P. Juneja an analytic in ${\mathbb D_0}=\{z:\,0<|z|<1\}$ function $f(z)=\frac{1}{z}+\sum_{n=1}^{\infty}f_n z^{n}$ is said to be meromorphically starlike of order $\alpha\in [0...
Divisor problem in special sets of Gaussian integers
Let $A_1$ and $A_2$ be fixed sets of gaussian integers. We denote by $\tau_{A_1, A_2}(\omega)$ the number of representations of $\omega$ in form $\omega=\alpha\beta$, where $\alpha \in A_1, \beta \in A_2$. We construct t...
On the multiplicative order of elements in Wiedemann's towers of finite fields
We consider recursive binary finite field extensions Ei+1=Ei(xi+1), i≥−1, defined by D. Wiedemann. The main object of the paper is to give some proper divisors of the Fermat numbers Ni that are not equal to the multiplic...
