Categories of Groups

Michal Muzalewski: Warsaw University, Bialystok

Summary.

We define the category of groups and its subcategories: category of Abelian groups and category of groups with the operator of $1/2$. The carriers of the groups are included in a universum. The universum is a parameter of the categories.
