In this paper we establish direct local and global approximation theorems for Baskakov type operators and Szász - Mirakjan type operators, respectively.
In this paper we show that the unit ball of an infinite dimensional commutative C*-algebra lacks strongly exposed points, so they have no predual. Also in the s
We extend the concept of frame multiresolution analysis to a locally compact abelian group and use it to define certain weighted Banach spaces and the spaces of
As a generalization of the Bernstein-Durrmeyer operators defined on the simplex, a class of general Bernstein- Durrmeyer operators is introduced. With the weigh
