Abstract: This paper answers the problem recently proposed by Hsu on identities involving the binomial coefficients and the two kinds of Stirling numbers. We explain Hsu's identities based on the well-known combinatorial interpretations of the two kinds of Stirling numbers.
Keywords: permutation; partition; Stirling numbers; combinatorial identity; counting number; modelling; combinatorics; binomial coefficients.
