چکیده

In this paper we study recurrences concerning the combinatorial sum k≡r (mod m) n k and the alternate sum k≡r (mod m) (−1) (k−r)/m n k , where m > 0, n 0 and r are integers. For example, we show that if n m − 1 then

EVALUATION OF SUMS INVOLVING GAUSSIAN q-BINOMIAL COEFFICIENTS WITH RATIONAL WEIGHT FUNCTIONS

We consider sums of the Gaussian q-binomial coefficients with a parametric rational weight function. We use the partial fraction decomposition technique to prove the claimed results. We also give some interesting applications of our results to certain generalized Fibonomial sums weighted with finite products of reciprocal Fibonacci or Lucas numbers.

Certain Sums Involving Inverses of Binomial Coefficients and Some Integrals

In this paper, we are concerned with sums involving inverses of binomial coefficients. We study certain sums involving reciprocals of binomial coefficients by using some integrals. Some recurrence relations related to inverses of binomial coefficients are obtained. In addition, we give the approximate values of certain sums involving the inverses of binomial coefficients.

Bernstein Basis Functions Related to Combinatorial Sums Involving Binomial Coefficients and Special Numbers

By using generating functions, which contained alternative forms, we derive identities, some new and old, for the Bernstein basis functions. Integrating these identities, we also derive combinatorial sums involving binomial coefficients. We give relations between these combinatorial sums and generating functions for special numbers, we investigate relations related to finite sums of the powers ...
