KOROVKIN TYPE APPROXIMATION THEOREMS ON THE SPACE OF CONTINUOUSLY DIFFERENTIABLE FUNCTIONS

摘要

It is studied Korovkin type approximation theorems on C~(1)([0,1]) the space of continuously differen- tiable functions on the unit interval. It is proved that the test functions for which Korovkin type approximation theorems hold depending on norms of C~(1)([0,1]).
