Binomial Convolution Preserves Log-Concavity.
Abstract
A sequence f = (f0, f1,...) of nonnegative numbers is log-concave if ln fi is a concave function of i. If two sequences f and g are both log-concave, then so is their binomial convolution. This complements the similar, well-known result for ordinary convolution. (Modified author abstract)
