It is well-known that if p is a homogeneous polynomial of degree k in n variables, p ∈ Pk, then the ordinary derivative p(■)(r^2-n) has the form An,kY(x)r2-n-
In this article, we obtain the L~p-boundedness of commutators of Lipschitz functions and singular integrals with non-smooth kernels on Euclidean spaces.
In this work, we study existence and uniqueness of solutions for multi-point boundary value problem of nonlinear fractional differential equations with two frac
This paper introduces a unified operator theory approach to the abstract Fourier analysis over homogeneous spaces of compact groups. Let G be a compact group an
We establish the construction theory of function based upon a local field K p as underlying space. By virture of the concept of pseudo-differential operator, we
