The lattice of
congruences on an inverse semigroup

Abstract |
|
The symmetry between four congruences which have figured in the literature on inverse semigroups is discussed in terms of kernels and restrictions to idempotents (kernel meaning the set of elements equivalent to idempotents). A characterization of arbitrary inverse semigroup congruences is developed from this symmetry. |
