On points avoiding measures
We say that an element $x$ of a topological space $X$ avoids measures if for every Borel measure $μ$ on $X$ if $μ(\{x\})=0$, then there is an open $U\ni x$ such that $μ(U)=0$. The negation of this property can viewed as a local version of the property of supporting a strictly positive measure. We study points avoiding measures in the general setting as well as in the context of $ω^\ast$, the remainder of Stone-Čech compactification of $ω$.
