Orbifolds as Stacks & Stringy Cohomology and Localization

Explore advanced mathematical concepts in this two-part lecture series delivered by Ernesto Lupercio from CINVESTAV. Begin with an in-depth examination of orbifolds as stacks, delving into twisted sectors and related topics. Then, transition to a comprehensive exploration of stringy cohomology, uncovering its properties through localization methods. Gain valuable insights into these complex mathematical subjects through clear explanations and expert analysis.
