On the log-concavity of $n$ -th root of a sequence

Ernest X. W. Xia, Zuo-Ru Zhang

In recent years, the log-concavity of ${n S_{n}}_{n \geq 1}$ have been received a lot of attention. Very recently, Sun posed the following conjecture in his new book: the se…

Asymptotic $r$ -log-convexity and P-recursive sequences

Qing-Hu Hou, Zuo-Ru Zhang

A sequence ${a_{n}}_{n \geq 0}$ is said to be asymptotically $r$ -log-convex if it is $r$ -log-convex for $n$ sufficiently large. We present a criterion on the asymptotical $r$ -log-…
