A Note on Two Theorems of C. Dong and J. Wang Concerning Combinatorial Identities


  •  Arnold R. Kräuter    

Abstract

In a recent paper C. Dong and J. Wang rederived three classical combinatorial identities by applying a special Vandermonde determinant. Two of their results, however, turn out to be incorrectly stated. This note presents counterexamples along with revised versions of the results mentioned.
