A generalization of Aztec diamond theorem, part II

摘要

The author gave a proof of a generalization of the Aztec diamond theorem for a family of 4-vertex regions on the square lattice with southwest-to-northeast diagonals drawn in Lai (2014) by using a bijection between tilings and non-intersecting lattice paths. In this paper, we use Kuo graphical condensation to give a new proof. (C) 2015 Elsevier B.V. All rights reserved.
