A variant of Tingley's problem for positive unit spheres of continuous functions that vanish at infinity

Kazuki Ezumi, Min-Ruei Lin, Takeshi Miura

Let $S(C_0(X){)}^{+}$ and $S(C_0(Y){)}^{+}$ denote the positive parts of the unit spheres of $C_0(X)$ and $C_0(Y)$, where $X$ and $Y$ are locally compact Hausdorff spaces. We prove that ev…
