摘要

我们研究了对称反半群、对偶对称反半群以及有限集的子项之间的双射的反半群的克罗内克系数的类似物。在所有情况下，我们都将确定这些系数的问题简化为一些群论和组合问题。对于对称反半群，我们用对称群的经典克罗内克系数和利特尔伍德-理查德森系数提供了一个明确的公式。

KRONECKER COEFFICIENTS FOR (DUAL) SYMMETRIC INVERSE SEMIGROUPS

We study analogues of Kronecker coefficients for symmetric inverse semigroups, for dual symmetric inverse semigroups and for the inverse semigroups of bijections between subquotients of finite sets. In all cases, we reduce the problem of determination of such coefficients to some group-theoretic and combinatorial problems. For symmetric inverse semigroups, we provide an explicit formula in terms of the classical Kronecker and Littlewood–Richardson coefficients for symmetric groups.
