    Hyperidentities are formulas in a second order language where quantification is allowed as well for individual variables as for operation symbols. This paper is a very nice survey on the theory of hyperidentities in semigroups, its model classes and applications. Several important and recent results and numerous open problems of this theory are presented.NEWLINENEWLINEFor the entire collection see [Zbl 0972.00067].
