The research is in the area of critical phenomena, a branch of condensed matter physics. The work consists in development of a method for the Monte Carlo diagonalization of huge matrices. Application is to an array of problems of high current interest in surface physics. The method is of multicisciplinary relevance, being related to techniques currently used to investigate the chemistry of many-electron systems. In addition the proposal encompasses various topics in the theory of phase transitions both of purely theoretical and of experimental importance.

这项研究是在临界现象领域进行的，这是凝聚态物理学的一个分支。本文的工作是发展一种巨型矩阵的蒙特卡罗对角化方法。应用于一系列目前在表面物理中高度感兴趣的问题。该方法具有多学科相关性，与目前用于研究多电子系统化学的技术有关。此外，该提案涵盖了相变理论中的各种问题，既有纯理论的，也有实验上的重要性。
