On the summability of spectral expansions of piecewise smooth functions

Аннотация

For piecewise smooth functions of n variables, we prove the uniform Riesz summability of order s > (n − 3)/2 of their spectral expansions associated with an arbitrary elliptic operator with constant coefficients. For s = (n − 3)/2, the corresponding Riesz means are bounded.
