Our research activity in this fiscal year has been mainly to summarize our research works in three years of this project. The research works were categorized into1. Study of string theories off criticality in the matrix models,2. Study of 2-dimensional quantum gravity,3. Study of the composite models for the Higgs mechanism in electroweak theory4. Study of the dynamical CP violation on composite Higgs models5. Analysis of the phase transition in field theory at finite temperature6. Study of the spontaneous breaking of supersymmetryIn order to summarize these works all investigators gathered in June and September in 1992 together with research assistants. From time to time we had small meetings for exchange of informations. In parallel with this project we had an international collaboration project with Fermilab theory group of U. S. A. in the same research subject. Under this program we had an international workshop in Hiroshima in November, 1992.The above research activity has been reviewed in the report 'Particle Physics and Symmetry'.

我们在本财政年度的研究活动主要是总结我们在该项目三年的研究工作。研究工作分为1.矩阵模型中脱离临界性的弦理论研究，2.二维量子引力的研究，3.电弱理论中Higgs机制的复合模型研究4.复合Higgs模型的动力学CP破坏研究5.有限温度下场论中的相变分析6.自发突破超验的研究为了总结这些工作，所有的研究人员和研究助理一起聚集在1992年6月和9月。我们不时举行小型会议，交换信息。与此同时，我们与美国费米实验室理论组进行了一个国际合作项目。S. A.同一个研究课题。根据这个计划，我们于1992年11月在广岛举办了一个国际研讨会。上述研究活动已在“粒子物理与对称性”报告中作了评论。
