$\Gamma$-supercyclicity of families of translates in weighted $L^p$-spaces on locally compact groups

Abstract

Let $\omega$ be a weight function defined on a locally compact group $G$, $1\le p<+\infty$, $S\subset G$ and let us assume that for any $s\in S$, the left translation operator $T_s$ is continuous from the weighted $L^p$-space $L^p(G,\omega)$ into itself. For a given set $\Gamma\subset\mathbb{C}$, a vector $f\in L^p(G,\omega)$ is said to be $(\Gamma,S)$-dense if the set $\{ \lambda T_sf:\, \lambda\in \Gamma, \,s\in S\}$ is dense in $L^p(G,\omega)$. In this paper, we characterize the existence of $(\Gamma,S)$-dense vectors in $L^p(G,\omega)$ in terms of the weight and the set $\Gamma$.
