    The Krohn-Rhodes complexity problem

    Friday 31st July, 12-1pm, Carslaw 273.

    The group complexity of a finite semigroup is the least number of group factors in a wreath product of finite groups and aperiodic semigroups which it divides. The talk will present recent advances on the problem as to whether such a parameter can be effectively computed.
