Decomposition of some Completely Regular Semigroups into Strong Semilattices of Semigroups

Open tomcontileslie opened this issue 5 years ago • 0 comments

May 2021 update: this PR has only ticked one of four boxes, but it works on Clifford semigroups. Implementing IsomorphismSemigroup for other types of completely regular semigroups can be done in a different PR.

This PR introduces methods for decomposing certain completely regular semigroups into strong semilattices, as suggested in Issue #671. The aim is introduce IsomorphismSemigroup methods from the following types of semigroups:

  • [X] Clifford semigroups
  • [ ] Normal orthogroups
  • [ ] Normal cryptogroups
  • [ ] Normal bands (?)

to SSS objects.
