Abstract:
We establish conditions for localization of generalised Riesz means of spectral decomposition by system of fundamental functions of Laplace operator in terms of belongingness of the decomposing function to the spaces of generalised smoothness.
Keywords and phrases:
spectral decompositions, summation method, principle of localization, spaces of generalised smoothness.
