|
|
- Update to new upstream release 2.1.1
|
|
* extensive new features for computing with elements and
|
|
subsemigroups of the partition monoid.
|
|
* support for ideals of transformation, partial permutation, and
|
|
bipartition semigroups, and subsemigroups of Rees 0-matrix
|
|
semigroups.
|
|
* The new operations IsomorphismSemigroups, IsIsomorphicSemigroup,
|
|
and SmallestMultiplicationTable.
|
|
* The new operation MaximalSubsemigroups, which returns the maximal
|
|
subsemigroups of an arbitrary semigroup.
|
|
* The new operation Normalizer for computing a subgroup of a
|
|
permutation group consisting of those permutations that stabilise,
|
|
under conjugation, a transformation, partial perm, or bipartition
|
|
semigroup.
|
|
* The new operation CharacterTableOfInverseSemigroup for finding the
|
|
character table of an inverse semigroup of partial permutations.
|
|
* Methods for defining and manipulating the congruences of a Rees
|
|
0-matrix semigroup.
|
|
* The operation EndomorphismsPartition that returns the monoid
|
|
of endomorphisms preserving a partition. This monoid is defined
|
|
using the minimum possible number of generators.
|
|
* A lot more, see the detailed changelog in the package.

|
|
|
|
- Update to new upstream release 1.4
|
|
* Package rename from citrus to semigroup. The package has been
|
|
completely overhauled, the performance has been improved, and the
|
|
code has been generalized so that in the future the same code can
|
|
be used to compute with other types of semigroups.
|
|
* This release includes several new methods for inverse semigroups
|
|
of partial permutations and for free inverse semigroup. Most
|
|
notably among the new methods for inverse semigroups of partial
|
|
permutations are: "SmallerDegreePartialPermRepresentation" and
|
|
"VagnerPrestonRepresentation" for changing the representation of
|
|
an inverse semigroup of partial permutations.
|
|
* The methods in Semigroups have been extended to apply to
|
|
arbitrary subsemigroups of regular Rees 0-matrix semigroups over
|
|
groups;
|
|
* A new method for MaximalSubsemigroups of Rees matrix semigroup
|
|
has been implemented;
|
|
* The function Read/WriteSemigroups have been renamed
|
|
Read/WriteGenerators and their performance has been improved. It
|
|
is now possible to use WriteGenerators to write to a gzipped file.
