On combinatorics of wreath product of finite symmetric inverse semigroups
Year:

Київський національний університет імені Тараса ШевченкаSome combinatorial results (eg cardinality of semigroup, combinatorics of Green’s relations, combinatorics of nilpotents) concerning wreath product of finite inverse symmetric semigroup are presented. Because of the recursive definition of the wreath product, a number of recurrent formulae, containing different types of known combinatorial objects, arises.
