Abstract: Abstract In proving Theorem 2.3 (Section 2.2) we have established a uniform (on an arbitrary compact set of domain G) equiconvergence of the Riesz means of order s of two arbitrary self-adjoint nonnegative extensions of the Laplace operator in domain G for a finite-in-G function f(x) belonging to one of the four classes [Eq3] with order of differentiability α > (N- 1)/2-s, where 0 ≤ s
