Danuta BorowskaProperties of the Minkowski subtraction of convex sets
In the talk we will define the Minkowski sum and subtraction in a semigroup. Furhtermore, we will prove some properties of the Minkowski subtraction, summands and the Sallee's sets in the semigropu . We will also discuss the full classification of strongly monotypic polyhedrons in and the relationship between the strongly monotypic polyhedrons and the Sallee's sets.
