Remarks on the commutation relations between the Gauss--Weierstrass semigroup and monomial weights

Abstract

We consider the commutation relations between the Gauss--Weierstrass semigroup on ${\mathbb{R}}^n$, generated by convolution with the complex Gaussian kernel, and monomial weights. We provide an explicit representation and a sharper estimate of the commutation relations with more concise proofs than those in previous works.
