This is a short survey on osicllatory integral operators. We summarize the main development and man-aging techniques of the field, and give some open problems a
It has been argued that Chebyshev polynomials are ideal to use as approximating functions to obtain solutions of integral equations and convolution integrals on
We present a class of the second order optimal splines difference schemes derived from ex-ponential cubic splines for self-adjoint singularly perturbed 2-point
In light of two measure estimate inequalities from [4] for the iterated Hardy-Littlewood maximal operator M~kf,certain equivalence between M~kf andthe Zygmund c
It is a classical result of Bernstein that the sequence of Lagrange interpolation polynomials to | x | at equally spaced nodes in [- 1,1] diverges everywhere, e
In this paper we consider a convolution operator Tf=p.v.Ω*f with Ω(x)=K(x)×e<sup>(r)</sup>λ】0.where K(x)is a weak Calderon-Zygmund kernel and h(x)is a real-value
