Abstract:The aim of the course is to study the Wieland method of invariant relations.The main topics include the m-equivalence and m-closures of permutation groups (m>=1), the behaviour of the m-closures with respect to the standard operations with permutation groups, and some efficient algorithms for finding the m-closure.
