In the present paper we study properties of Szász-Durrmeyer operators. These operators are introduced in [5] and generalize the integral operators proposed
Let L be an elliptic operator, we give arguments about the duality estimate between Morrey spaces and its pre-dual spaces characterized by the heat kernel assoc
<正>The current paper considers the problem of recovering a function using a lim- ited number of its Fourier coefficients.Specifically,a method based on Bemoull
