We give a brief introduction to results on the asymptotics of quantization errors.The topics discussed include the quantization dimension,asymptotic distributio
Let X= Rn+ × R denote the underlying manifold of polyradial functions on the Heisenberg group Hn.We construct a generalized translation on X=Rn+ × R,
In this paper, we use weighted modules ω2φλ (f,t)w to study the pointwise approximation on Szász-typeoperators, and obtain the direct and converse theor
Lp(Rn) boundedness is considered for the multilinear singular integral operator defined by TAf(x) = ∫Rn Ω(x - y)/|x - y|n+1 (A(x) - A(y) - (△)A(y)(x - y))f(y
