L_p-approximation by multidimensional Gauss-Weierstrass operators
Wang Jianli(Shaoxing Teacher's Collage)
In this paper,the characterization of multimensional Gauss-Weierstrass operators Wn,m(F;x,y)are considered.for f ∈Lp(R2) 1p≤∞,Oα1,then the following statements are equivalent each to another:(i) K1.2(F,t)= O(t°);
