- 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.
