Symmetric polynomials on the Cartesian power of Lp on the semi-axis
Journal Title: Математичні Студії - Year 2018, Vol 50, Issue 1
Abstract
The paper deals with polynomials in the complex Banach space (Lp[0,+∞))n, which are the nth Cartesian power of the complex Banach space of Lebesgue measurable integrable in a power p complex-valued functions on [0,+∞), where 1≤p≤+∞. It is proved that if p is an integer, then every continuous symmetric polynomial on (Lp[0,+∞))n can be uniquely represented as an algebraic combination of some ``elementary'' p-homogeneous symmetric polynomials. It is also proved that if p is not an integer, then every continuous symmetric polynomial on (Lp[0,+∞))n is constant. Results of the paper can be used for investigations of algebras of symmetric continuous polynomials and of symmetric analytic functions on (Lp[0,+∞))n.

On uniqueness of entropy solutions for nonlinear elliptic degenerate anisotropic equations
In the present paper we deal with the Dirichlet problem for a class of degenerate anisotropic elliptic second-order equations with L1-right-hand sides in a bounded domain of Rn (n⩾2). This class is described by the prese...
New generalizations of Sierpinski theorem(in Ukrainian)
We introduce the notion of equi-feeblycontinuity which ressembles S. Kempisty's equi-quasicontinuity. Using this fresh notion and weak horizontal quasicontinuity, we obtain new generalizations of Sierpinski theorem on se...

Visco-plastic, newtonian, and dilatant fluids: Stokes equations with variable exponent of nonlinearity
Some nonlinear Stokes equations with variable exponent of the nonlinearity are considered. The initial-boundary value problem for these equations is investigated and the existence of the weak and very weak solutions for...
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.
