Random Sampling of Contingency Tables via Probabilistic Divide-and-Conquer

Stephen DeSalvo, James Y. Zhao

We present a new approach for random sampling of contingency tables of any size and constraints based on a recently introduced $probabilistic divide-and-conquer$ technique…

Sun's log-concavity conjecture on the Catalan-Larcombe-French sequence

James J. Y. Zhao

Let ${P_{n}}_{n \geq 0}$ denote the Catalan-Larcombe-French sequence, which naturally came up from the series expansion of the complete elliptic integral of the first kind. In this…

Log-concavity of the Fennessey-Larcombe-French Sequence

Arthur L. B. Yang, James J. Y. Zhao

We prove the log-concavity of the Fennessey-Larcombe-French sequence based on its three-term recurrence relation, which was recently conjectured by Zhao. The key ingredient of our…
