General types of spherical mean operators and k-functionals of fractional orders
Communications on Pure and Applied Analysis, Springfield, v. 14, n. 3, p. 743-757, May 2015
We design a general type of spherical mean operators and employ them to approximate 'L IND.P' class functions. We show that optimal orders of approximation are achieved via appropriately defined K-functionals of fractional orders.
