Fractional Smoothness in
$L^p$
with Dunkl Weight
and Its Applications
D. V. Gorbachev, V. I. Ivanov Tula State University, Tula, 300012 Russia
Abstract:
We define a fractional power of the Dunkl Laplacian, a fractional modulus of smoothness,
and a fractional
$K$-functional on
$L^p$-spaces with Dunkl weight.
As an application, we extend our previous results and prove direct and inverse theorems of
approximation theory and some inequalities for entire functions of spherical
exponential type in the fractional setting.
Keywords:
Dunkl transform, generalized translation operator, convolution,
Dunkl Laplacian, modulus of smoothness,
$K$-functional.
