UDC 514.172 In the present work, we consider a class of generalized convex sets in the real plane known as weakly $1$-convex sets. For a set in the real Euclidean space $\mathbb{R}^n,$ $n\ge 2,$ it is said that a point of the complement of this set to the whole space $\mathbb{R}^n$ is an $\boldsymbo...
