Group Coextensions

  • P. A. Grillet
Part of the Advances in Mathematics book series (ADMA, volume 2)


Group coextensions were developed independently by Grillet [1974] and Leech [1975] for semigroups in general. They yield precise constructions of complete commutative semigroups in terms of abelian groups and group-free semigroups. This leads to the semigroup cohomology which is studied in the last chapters of this book.
