Simultaneous approximation by polynomials in Orlicz spaces generated by quasiconvex Young functions
In this paper we prove some theorems on simultaneous approximation by trigonometric or algebraic polynomials in Orlicz spaces constructed by Young functions belonging to a reasonably wide class.

On large sieve inequalities involving pth powers of trigonometric polynomials
In this paper, we extend the large sieve type estimates to sums involving pth powers of trigonometric polynomials. An approach to such estimates that does not rely on the usual L^2-technique is given.

Algorithms for Various Trigonometric Power Sums
In this paper, algorithms for different types of trigonometric power sums are developed and presented. Although interesting in their own right, these trigonometric power sums arise during the creation of an algorithm for the four types of twisted ...

Positive trigonometric polynomials
We study the boundary of the nonnegative trigonometric polynomials from the algebraic point of view. In particularly, we show that it is a subset of an irreducible algebraic hypersurface and established its explicit form in terms of resultants.

Anti-Gaussian quadrature rule for trigonometric polynomials
An anti-Gaussian quadrature formula is an (n+1)-point formula with algebraic degree of exactness 2n + 1. Its error is equal in magnitude but of opposite sign to that of the n-point Gaussian formula.
