Our main purpose is the solution of the problem of shadow for a family of balls with fixedradius in the n-dimensional Euclidean space. Many similar problems were studied in the works of one ofthe authors and his disciples. This problem can be considered as the establishment of minimal conditionsto ensure the membership of a point to the generalized...

n-мерном евклидовом пространс-тве. Широкий спектр таких задач исследовался в работах одного из авторов и его учеников. Эту задачу можно рассматривать как на-хождение минимальных условий обеспечивающих принадлежность точки обобщенно выпуклой оболочке семейства шаров фиксирован-ного радиуса. 2010 MSC. 52A01, 52A30, 26B25. Ключевые слова и фразы. Евкл...

Multivalued isolated mappings are investigated. We describe a behaviour of such mappings on the exclusive set and conditions of their extention. Дослiджуються многозначнi нульвимiрнi вiдображення. Встановлена поведiнка таких вiдображень на особливих множинах та умови сти-рання особливостей. В работе рассмотрим многозначные отображения областей на м...

We establish an external criterion for the convexity of a domain of a Euclidean space. The aim of the present paper is to establish a criterion for the convexity of a domain on the basis of some external characteristics of this domain. For this purpose, we use notions introduced in [1] and topological terms [2]. Let ′ − G n n (,) 2 denote the Grass...
