In this paper we introduce a kind of kernels called δ-kernels.Based on them linear opera-tors from the continuous mapping space to R~m are constructed.We give
A.simplicial mesh(triangulation)is constructed that generalizes the two-dimensional 4-directionmesh to R~m.This mesh,with symmetric,shift-invariant values at th
The logical derivatives of p-adic copy-shift and shift-copy generalized Bridge functions are given in this paper. When p equals 2, they are exactly the logical
We modify Bernstein-Durrmeyer operators by means of digonal matarix which overeome a difficulty inextending a Berens-Lorentz result to the Bernstein-Durrmeyer o

Suppose that C is the complex plane and k is a non-negative integer.Define functions Nk-(x)=|x|k if k is even and Nk(x)=x|x|k-1 if k is odd.Some approximation p
