On finite exhausters
The seminar will take place in room A2-22 at 11.30
We will introduce the notion of a shadowing set, which is a generalization of the notion of separating set to the family of more than two sets. Then we will give a criterion for an upper exhauster to be an exhauster of sublinear function as well as the criterion for minimality of finite upper exhauster.
