项目摘要

In this project we have mainly studied brain dynamics and duality in superstring theory from various angles.It is important to discuss the compactification on special holonomy manifolds in order to realize space-time supersymmetry in the context of string theory. Eguchi and Sugawara have been studying the superstring theory compactified on special holonomy manifolds and D-branes in this background from the viewpoints of the world-sheet superconformal theory. As related works, Sugawara also studied the string theory on NS5 brane background and AdS3 space. Eguchi also gave a detailed analysis on the geometry associated to higher dimensional SUSY gauge theory with the helps of mirror symmetry and succeeded in constructing the exact forms of Seiberg-Witten curves for the 5 and 6 dimensional SUSY gauge theories.In recent years the tachyon condensation in open siring theory and D-brane dynamics have been intensively studied with the helps of non-commutative geometry and open string field theory. Matsuo and Kawano independently presented series of works for this subject. Matsuo studied the non-commutative solitons on non-commutative torus and discussed their brane interpretation. He also studied the open stiring field theory around the vacuum at which tachyons condenstate (VSFT) and argued on the role of identity projector, for example. Kawano explored aspects of open string field theory with non-zero B-field. He further studied the fluctuation modes around classical solutions in VSFT and discussed the identification with the modes of open string theory.Imamura, who joined this project in the last year, studied BPS classical solutions in the massive type 11A supergravjty and argued on the identification with the system of intersecting branes.

在这个项目中，我们主要研究了从各个角度研究超弦理论中的脑动力学和二元性。重要的是要在弦理论的背景下讨论特殊载体歧管的紧凑型，以实现时空超对称性。 Eguchi和Sugawara一直在研究从世界地面超构造理论的角度来研究这种背景的特殊载体歧管和d-branes的superstring理论。作为相关作品，Sugawara还研究了NS5 Brane背景和ADS3空间的字符串理论。 Eguchi还对与较高维度的SUSY仪表理论相关的几何形状进行了详细的分析，并有助于对镜子对称性进行帮助，并成功地构建了5和6尺寸SUSY量学理论的Seiberg-Witten曲线的确切形式。近年来，开放的Siring理论和D-Brane Dynamics的Tachyon凝结在不合格的范围内进行了启用，并进行了无线电图的范围。 Matsuo和Kawano独立地为此主题展示了一系列作品。 Matsuo研究了非共同的孤子，并讨论了他们的勃雷解释。他还研究了Tachyons Condenstate（VSFT）的真空周围的开放式搅拌场理论，例如，介绍了身份投影仪的作用。川诺（Kawano）用非零B场探索了开放字段理论的各个方面。他进一步研究了VSFT中经典解决方案围绕经典解决方案的波动模式，并与开放式弦乐理论的模式讨论了识别。Mimamura在去年加入了该项目，研究了BPS经典解决方案，以11A型Supergravjty型，并与相交Branes系统的识别进行了争论。
