R.Taberski, Approximation properties of the integral Bernstein oper- ators and their derivatives in some classes of locally integrable
Inequalities are derived which enable one to estimate in- tegral moduli of continuity of functions of several variables in terms of Fourier coefficients.. In the paper inequalities
U. In this paper we study the approximation by rectangular partial sums of a double Fourier series with respect to the Walsh–Kaczmarz system in the spaces C and L. From our results
By means of piecewise continuous auxiliary functions which are analogues of the classical Lyapunov’s functions, sufficient con- ditions are obtained for the existence of
In this paper we derive some criteria for univalence of analytic functions and of an integral operator in the open unit disk.. 2000 Mathematics Subject
He established the partial differential equation governing heat diffusion and solved it by using infinite series of trigonometric functions.. Fourier also appears to have been the
