A Sharp Jackson Inequality in $L_p(\mathbb R^d)$ with Dunkl Weight
D. V. Gorbachev, V. I. Ivanov Tula State University
Abstract:
A sharp Jackson inequality in the space $L_p(\mathbb R^d)$, $1\le p<2$, with Dunkl weight is proved. The best approximation is realized by entire functions of exponential spherical type. The modulus of continuity is defined by means of a generalized shift operator bounded on $L_p$, which was constructed earlier by the authors. In the case of the unit weight, this operator coincides with the mean-value operator on the sphere.
Keywords:
Dunkl transform, best approximation, generalized shift operator, modulus of continuity, Jackson inequality.
