On the probabilistic metrizability of approach spaces (2408.07548v1)

Abstract: We investigate approach spaces generated by probabilistic metric spaces with respect to a continuous t-norm $$ on the unit interval $[0,1]$. Let $k^$ be the supremum of the idempotent elements of $$ in $[0,1)$. It is shown that if $k^=1$ (resp. $k^*<1$), then an approach space is probabilistic metrizable with respect to $*$ if and only if it is probabilistic metrizable with respect to the minimum (resp. product) t-norm.
