项目摘要

T, Yoneya studied various possibilities towards field theory of D-branes. In particular, he has constructed a 2^<nd> quantized representation of 1/2-BPS operators in the Yang-Mills theory for D3-branes. Furthermore, he has proposed an entirely new theoretical framework for a general method of 2^nd quantization of D-particles. He has also established the correspondence between the two-point correlation functions and the S-matrix of the c=1 matrix model, by applying his previous proposals for the space-time interpretation of holographic principle in the so-called BMN limit. He has also applied the same method for investigating the property of Wilson loops with local operator insertions in the Yang-Mills theory.Y. Kazama has studied the pure-spinor formalism for the purpose of constructing manifestly covariant quantum theory of superstrings and supermembranes. In particular, he has proposed a double-spinor formalism as an extension of the usual pure-spinor formalism, and applied it to sup … More ermembranes and derived the algebra of first-class constraints.M. Kato has studied the structure of string-field theory. He has proposed a new gauge condition in the covariant open-string field theory of Witten, and applied it to an investigation of the effective potential for the tachyon mode. He has shown that the known singularity in the Siegel gauge is unphysical and succeeded to obtain a smooth effective potential.K. Hashimoto has studied various aspects of the dynamics of D-branes. In particular, he has applied the so-called AdS/CFT correspondence to QCD, and studied the phenomenon of chiral symmetry breaking from this viewpoint. He has also investigated the recombination of cosmic strings using D-branes and also the property of soliton solutions in meta-stable vacuua of gauge theories violating supersymmetry.S. Odake has carried out various studies on solvable quantum mechanical systems. In particular, he has studied one-dimensional systems using the sinusoidal coordinates in the Heisenberg representation, and succeeded to give a unifed and general definition for creation and annihilation operators in such systems, with applications to discrete quantum mechanics.

T，Yoneya 研究了 D 膜场论的各种可能性。特别是，他在 D3 膜的 Yang-Mills 理论中构建了 1/2-BPS 算子的 2^<nd> 量化表示。此外，他还为 D 粒子的二次量子化的通用方法提出了一个全新的理论框架。他还通过应用他之前提出的在所谓的 BMN 极限下对全息原理的时空解释的建议，建立了两点相关函数和 c=1 矩阵模型的 S 矩阵之间的对应关系。他还应用相同的方法来研究在 Yang-Mills 理论中插入局部算子的威尔逊环的性质。风间研究了纯旋量形式主义，目的是构建超弦和超膜的明显协变量子理论。特别是，他提出了双旋量形式主义作为通常的纯旋量形式主义的扩展，并将其应用于支持膜并导出了第一类约束的代数。加藤研究了弦场理论的结构。他在维滕的协变开弦场理论中提出了一种新的规范条件，并将其应用于快子模式有效势的研究。他证明了西格尔规范中已知的奇点是非物理的，并成功地获得了平滑的有效势。桥本研究了 D 膜动力学的各个方面。特别是，他将所谓的AdS/CFT对应应用于QCD，并从这个角度研究了手性对称性破缺的现象。他还研究了使用 D 膜进行的宇宙弦重组，以及违反超对称性的规范理论亚稳真空中孤子解的性质。 Odake 对可解的量子力学系统进行了各种研究。特别是，他研究了使用海森堡表示中的正弦坐标的一维系统，并成功地为此类系统中的创建和湮灭算子给出了统一且通用的定义，并将其应用于离散量子力学。较少的
