随机矩阵与Laplacian增长

Random matrices and Laplacian growth

A. Zabrodin

摘要:

随机矩阵的理论与特征值分布在复杂的平面和更一般的“β-系综”(对数气体在2D)进行审查。在大N极限下研究了特征值的分布和相关性。它表明,在这个限制的模型是数学上等价于一类扩散控制的增长模型的Hele-Shaw细胞和其他的拉普拉斯型的增长过程中的粘性流动。所使用的分析方法涉及技术的边界值问题在两个维度和潜在的理论元素。

英文摘要:

The theory of random matrices with eigenvalues distributed in the complex plane and more general "beta-ensembles" (logarithmic gases in 2D) is reviewed. The distribution and correlations of the eigenvalues are investigated in the large N limit. It is shown that in this limit the model is mathematically equivalent to a class of diffusion-controlled growth models for viscous flows in the Hele-Shaw cell and other growth processes of Laplacian type. The analytical methods used involve the technique of boundary value problems in two dimensions and elements of the potential theory.
