Unimodality and log-concavity of generalized Glasby-Paseman sequences
Seok Hyun Byun, Svetlana PoznanoviÄ
In this paper, we consider a two-parameter ( and ) generalization of a sequence that Glasby and Paseman considered. Based on computer experiments, we conjecture its unimodali…

Lozenge Tilings of Hexagons with Intrusions I: Generalized Intrusion
Seok Hyun Byun, Tri Lai
MacMahon's classical theorem on the number of boxed plane partitions has been generalized in several directions. One way to generalize the theorem is to view boxed plane partitions…
