A new recursive construction for large sets of Kirkman triple systems
Chen Wang
We give a recursive construction of an LKTS(7q + 2) from an LKTS(q + 2) and an auxiliary permutation structure on an abelian group of order q, which we call a cubic orthomorphism.…
Two supercongruences involving truncated hypergeometric series
Wei Xia, Chen Wang
In this paper, we mainly establish two supercongruences involving truncated hypergeometric series by using some hypergeometric transformation formulas. The first supercongruence co…
Supercongruences arising from a hypergeometric transformation formula
Chen Wang
Using a hypergeometric transformation formula, we prove two supercongruences. In particular, one of these supercongruences confirms a recent conjecture of Guo, Liu and Sc…
Tight Regret Bounds for Single-pass Streaming Multi-armed Bandits
Chen Wang
Regret minimization in streaming multi-armed bandits (MABs) has been studied extensively in recent years. In the single-pass setting with arms and trials, a regret lower bo…
