Gal S.G. Overconvergence in Complex Approximation

Springer Science+Business Media, New York, 2013. — 206 p. — ISBN10: 1461470978It is a well-known fact that the concept of overconvergence in approximation theory may have several meanings. The most common, developed for the first time by Ostrovski and Walsh, is that given a sequence of functions approximating a given (analytic) function in a set (region), the convergence may hold not merely in that set, but in a larger one containing the first set in its interior.Overconvergence in C of Some Bernstein-Type Operators
