Champagne subdomains with unavoidable bubbles

Wolfhard Hansen, Ivan Netuka

A champagne subdomain of a connected open set $U \neq = \emptyset$ in $R^{d}$ , $d \geq 2$ , is obtained omitting pairwise disjoint closed balls $B ˉ (x, r_{x})$ , $x \in X$ , the bubbles, where…

Convexity of limits of harmonic measures

Wolfhard Hansen, Ivan Netuka

It is shown that, given a point $x\in\mathbbm{R}^d$, $d \geq 2$ , and open sets $U_{1}, ..., U_{k}$ containing $x$ , any convex combination of the harmonic measures for $x$ with respect to $…
