Summability of Hermite expansions. II

Author:

Thangavelu S.

Abstract

We study the summability of n n -dimensional Hermite expansions where n > 1 n > 1 . We prove that the critical index for the Riesz summability is ( n 1 ) / 2 (n - 1)/2 . We also prove analogues of the Fejér-Lebesgue theorem and Riemann’s localisation principle when the index α \alpha of the Riesz means is > ( 3 n 2 ) / 6 > (3n - 2)/6 .
