Abstract

In this paper, we prove the qq-log-convexity of Domb's polynomials, which was conjectured by Sun in the study of Ramanujan-Sato type series for powers of π\pi. As a result, we obtain the log-convexity of Domb's numbers. Our proof is based on the qq-log-convexity of Narayana polynomials of type BB and a criterion for determining qq-log-convexity of self-reciprocal polynomials.
