Shelly Wismath - Hyperidentities for varieties of star bands

A hyperidentity of a variety of algebras is an identity which holds in an additional stronger way. This talk will give an introduction and short overview of the study of hyperidentities, then present some joint work with J. Koppitz on the hyperidentities satisfied by the varieties of star-bands. This is based on an equational description of the lattice of all varieties of star-bands given by Adair and by Petrich.
