In this note,we define a new kind of spaces TF of Triebel-Lizorkin type and characterize it via sequence space lp Also a Fourier multiplier theorem is establish
For the numerical evaluation of Cauchy principal value integrals of the form f(x)(x - λ) -1dx withλ ∈ (-1,1)and f ∈ C1[-1,1], we investigate the quadrature
In this paper, we first discuss the methods of comparing two special absolutely convergentsine series, sinnx and sinnx. We state the theorem in.one dimensional
