Lattice renormings of $C_0(X)$ spaces

Abstract

Suppose $X$ is a locally compact Polish space, and $G$ is a group of lattice isometries of $C_0(X)$ which satisfies certain conditions. Then we can equip $C_0(X)$ with an equivalent lattice norm $|||\cdot |||$ so that $G$ is the group of lattice isometries of $(C_0(X),|||\cdot |||)$. As an application, we show that for any locally compact Polish group $G$ there exists a locally compact Polish space $X$, and an lattice norm $|||\cdot |||$ on $C_0(X)$, so that $G$ is the group of lattice isometries of $(C_0(X),|||\cdot |||)$.
