Recurrence Relations for Strongly q-Log-Convex Polynomials
William Y.C. Chen, Larry X.W. Wang and Arthur L.B. Yang
Abstract: We consider a class of strongly q-log-convex polynomials based on a triangular recurrence relation with linear coefficients, and we show that the Bell polynomials, the Bessel polynomials, the Ramanujan polynomials and the Dowling polynomials are strongly q-log-convex. We also prove that the Bessel transformation preserves log-convexity.
