In this paper we study the regularity properties of the Gaussian Bessel potentials and Gaussian Bessel fractional derivatives on variable Gaussian Besov-Lipschitz spaces $B_{p(\cdot),q(\cdot)}^{\alpha}(\gamma_{d}),$ that were defined in a previous paper \cite{Pinrodurb}, under certain conditions on $p(\cdot)$ and $q(\cdot)$.
In a previous paper two of the authors introduced and study Gaussian Besov-Lipschitz spaces $B_{p,q}^{\alpha}(\gamma_{d})$ and Gaussian Triebel-Lizorkin spaces $F_{p,q}^{\alpha}(\gamma_{d})$. Now, in this paper we introduce the variable Gaussian Besov-Lipschitz spaces $B_{p(\cdot),q(\cdot)}^{\alpha}(\gamma_{d})$ and the variable Gaussian Triebel-Lizorkin spaces $F_{p(\cdot),q(\cdot)}^{\alpha}(\gamma_{d}),$ that is to say, Gaussian Besov-Lipschitz and Triebel-Lizorkin spaces with variable exponents, under certain additional regularity conditions on the exponents $p(\cdot)$ and $q(\cdot)$ introduced by Dalmasso and Scotto. Trivially, they include the Gaussian Besov-Lipschitz spaces $B_{p,q}^{\alpha}(\gamma_{d})$ and Gaussian Triebel-Lizorkin spaces $F_{p,q}^{\alpha}(\gamma_{d})$. We consider some inclusion relations of those spaces and finally we also prove some interpolation results for them.
