A sequence (an)n>0 of natural numbers is said to be log-concave (resp. log-convex) if a2 n+1 > anan+2 (resp. a 2 n+1 6 anan+2) for all n = 0, 1, 2, . . .. The log-concavity or log-convexity of… (More)

In this paper we derive a general combina torial identity in terms of polynomials with dual sequences of coefficients. Moreover, combin atorial identities invol ving Bernoulli and Euler polynomials… (More)

Let p be a prime and let a be a positive integer. In this paper we determine ∑pa−1 k=0 ( 2k k+d ) /mk and ∑p−1 k=1 ( 2k k+d ) /(kmk−1) modulo p for all d = 0, . . . , pa, where m is any integer not… (More)

For n = 1, 2, 3, . . . define S(n) as the smallest integer m > 1 such that those 2k(k − 1) mod m for k = 1, . . . , n are pairwise distinct; we show that S(n) is the least prime greater than 2n− 2… (More)
