In particular we fo- cus on the structure of the moduli space of special Lagrangian subamanifolds studied by Hitchin. In the second part, we focus on the theory of Lagrangian mean curvature flow, especially the Lagrangian self-similar solutions constructed by Joyce- Lee-Tsui. At the end we describe an unsolved conjecture given by Thomas and Yau.口試委員會審定書 i 致謝 ii 中文摘要 iii Abstract iv Contents iv 1 Introduction 1 2 Preliminaries 3 2.1 Calabi-YauManifolds............................ 3 2.2 Lagrangian Submanifolds.......................... 4 2.3 Special Lagrangian Submanifolds ..................... 8 3 Moduli Space of Special Lagrangian Submanifolds 12 3.1 Deformations of Special Lagrangian Submanifolds . . . . . . . . . . . . 12 3.2 Local Coordinates on the Moduli Space M ................ 13 3.3 Lagranigan structure on M ......................... 16 3.4 Kahler Structure on the Complexified Moduli Space. . . . . . . . . . . . 18 3.5 The SYZ conjecture............................. 22 4 Lagrangian Mean Curvature Flow 23 4.1 Introduction to Lagrangian Mean Curvature Flow . . . . . . . . . . . . . 23 4.2 Singularities of Lagrangian Mean Curvature Flow . . . . . . . . . . . . . 26 4.3 Self-similar Solutions............................ 29 4.4 The Brakke motion ............................. 31 5 The Joyce-Lee-Tsui Self-similar Solutions 33 5.1 Construction of Self-similar Solutions ................... 33 5.2 Self-expanders ............................... 37 5.3 A Brakke Motion Coming Out From a Lagrangian Cone. . . . . . . . . . . 41 6 The Thomas-Yau Conjecture 44 6.1 The moment map .............................. 44 6.2 Lagrangian Surgeries ............................ 45 6.3 The Thomas-Yau Stability ......................... 46949751 bytesapplication/pdf論文公開時間:2014/08/21論文使用權限:同意有償授權(權利金給回饋學校)均曲率流拉格朗日子流形特殊拉格朗日子流形卡拉比 -丘流形中的拉格朗日和特殊拉格朗日子流形Lagrangian and Special Lagrangian Submanifolds in a Calabi-Yau Manifoldthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/264015/1/ntu-103-R01221006-1.pdf
