A remarkable sequence of integers
A survey of properties of a sequence of coefficients appearing in the
evaluation of a quartic definite integral is presented. These properties are of
analytical, combinatorial and number-theoretical nature.Comment: 20 pages, 5 figure
An Extension of a Criterion for Unimodality
We prove that if P(x) is a polynomial with nonnegative nondecreasing coefficients and n is a positive integer, then P(x+n) is unimodal. Applications and open problems are presented
