Markov's inequality and functions on algebraic sets
Tomasz Beberok
It is known that for determining sets Markov's property is equivalent to Bernstein's property. The purpose of this paper is to prove an analogous result in the case of…

boundedness of the Bergman projection on the generalized Hartogs triangles
Tomasz Beberok
In this paper we investigate a two classes of domains in generalizing the Hartogs triangle. We prove optimal estimates for the mapping properties of the Bergman proj…
