题目:Hull-Strominger system and anomaly flow on Riemann surfaces 报告人:费腾 报告时间:2018年元月4号下午3:00 报告地点:数理楼145报告厅 摘要: The Hull-Strominger system is a system of nonlinear PDEs describing the geometry of compactification of heterotic strings with torsion, which can be thought of as a generalization of Ricci-flat Kahler metrics coupled with Hermitian-Yang-Mills equation on non-Kahler Calabi-Yau 3-folds. The Anomaly flow is a parabolic approach to understand the Hull-Strominger system invented by Phong-Picard-Zhang. We show that in the setting of generalized Calabi-Gray manifolds, the Hull-Strominger system and the Anomaly flow reduce to interesting elliptic and parabolic equations on Riemann surfaces. By solving these equations, we found solutions to the Hull-Strominger system on compact non-Kahler Calabi-Yau 3-folds with infinitely many topological types and sets of Hodge numbers. This talk is based on joint work with Zhijie Huang and Sebastien Picard. 报告人简历:费腾博士,2011年清华大学数学系本科毕业,2016年获麻省理工学院(MIT)数学博士学位。现在哥伦比亚(Columbia)大学担任J. F. Ritt Assistant Professor一职(非终身轨的助理教授
