WebOct 3, 2008 · Abstract.In a recent note, Santana and Diaz-Barrero proved a number of sum identities involving the well-known Pell numbers. Their proofs relied heavily on the Binet formula for the Pell numbers. Our goal in this note is to reconsider these identities from a purely combinatorial viewpoint. We provide bijective proofs for each of the results by … http://mathonline.wikidot.com/binomial-coefficient-identities WebOct 28, 2009 · 1. Introduction. Calkin [4] proved a curious identity of sums of 3-powers of the partial sum of binomial coefficients: (1.1) Hirschhorn [6] established some recurrence relations of sums of powers of the partial sum of binomial coefficients, and obtained (1.2) (1.3) and Calkin’s identity.
