Remarks to Glazek's results on n-ary groups

Abstract

It is a survey of the results obtained by K. G lazek's and his coworkers. We restrict our attention to the problems of axiomatizations of n-ary groups, classes of n-ary groups, properties of skew elements and homomorphisms induced by skew elements, constructions of covering groups, classifications and representations of n-ary groups. Some new results are added too.
