Some algebraic identity and its relations to Stirling numbers of the second kind
arxiv（2022）
摘要
In this short note we provide some algebraic identity with a proof exploiting its probabilistic interpretation. We show several consequences of the identity, in particular we obtain a new representation of a Stirling number of second kind, $$ S(n,d)={1\over d!} \sum_{1\leq j_1更多
