阿兹特克钻石的交错颗粒系统和镶嵌

Interlaced particle systems and tilings of the Aztec diamond

Benjamin J. Fleming, Peter J. Forrester

摘要:

受阿兹特克钻石多米诺骨牌问题的启发,在$N$线上定义了一个加权粒子系统,其中线$j$包含$j$粒子。粒子被限制为从0到$N$的晶格点,并且连续线上的粒子受到交错约束。结果表明,该粒子系统的边缘分布可以精确计算。这反过来又被用来给统一推导的一些基本属性的平铺问题,例如评估的数量不同的配置和关系的GUE未成年人过程。一个交错的粒子系统与多米诺骨牌瓷砖的某一半阿兹特克钻石类似的定义和分析。

英文摘要:

Motivated by the problem of domino tilings of the Aztec diamond, a weighted particle system is defined on $N$ lines, with line $j$ containing $j$ particles. The particles are restricted to lattice points from 0 to $N$, and particles on successive lines are subject to an interlacing constraint. It is shown that marginal distributions for this particle system can be computed exactly. This in turn is used to give unified derivations of a number of fundamental properties of the tiling problem, for example the evaluation of the number of distinct configurations and the relation to the GUE minor process. An interlaced particle system associated with the domino tiling of a certain half Aztec diamond is similarly defined and analyzed.
