Theory of schemes and stacks, Derived Categories and Intersection theory II
This course is targeting 3 major segments of algebraic geometry. The theory of schemes and stacks following Grothendieck’s EGA / SGA and Deligne’s work on stacks. The derived category of coherent sheaves, its properties and relevance to birational geometry and moduli theory, and intersection theory on schemes and stacks. Students who passed a basic course in algebraic geometry (e.g. Hartshorne’s first 3 chapters) must be able to follow the course with no further pre-requisite. The course will offer an extensive analysis of all three segments and aims at providing the detailed background for algebraic geometry students to perform advanced research on geometry of schemes and moduli, say in the context of birational geometry, enumerative algebraic geometry or derived algebraic geometry.

讲师介绍
Artan Sheshmani主要研究方向为代数几何、 微分几何和弦理论的数学方面。他于2022年加入BIMSA任研究员一职,曾任哈佛大学数学科学及其应用研究所(CMSA)西门斯同调镜像对称合作项目资深成员(教授),及美国哈弗-麻省理工人工智能和基本交互作用研究所成员。
2020年至2023年期间,他在美国迈阿密大学美国数学科学研究所担任访问教授一职,并参与了关于“霍奇理论及其应用”的研究合作项目。2020-2022年,他在哈佛大学物理系担任访问教授。2016-2022年,他在丹麦奥胡斯大学数学学院(原量子几何与模空间中心)担任副教授。
他的主要研究方向集中在Gromov Witten理论、Donaldson Thomas理论、Calabi-Yau几何以及弦理论的数学方面。他研究在Calabi Yau空间上的束和曲线的模空间的几何学,其中部分工作在研究弦理论理论的数学方面起到重要作用。在他的研究中,他致力于理解在复变化的各个维度上的这些模空间的几何对偶性,并目前正在从导出几何和几何表示理论的角度拓展这些项目。
