Abstract

Wreath products involving symmetric inverse monoids/semigroups/categories arise in many areas of algebra and science, and presentations by generators and relations are crucial tools in such studies. The current paper finds such presentations for MInM\wr\mathcal I_n, MSing(In)M\wr\operatorname{Sing}(\mathcal I_n) and MIM\wr\mathcal I. Here MM is an arbitrary monoid, In\mathcal I_n is the symmetric inverse monoid, Sing(In)\operatorname{Sing}(\mathcal I_n) its singular ideal, and I\mathcal I is the symmetric inverse category.
