General Mathematics Colloquium
Speaker: Ezra Getzler (Northwestern University, IL, USA)
In the theory of differential graded algebras (important in the study of moduli problems in geometry, for example), the correct generalization of invertibility is invertibility up to a boundary, or quasi-invertibility. In this talk, we will explain in what sense the quasi-invertible elements form a "Lie group". In fact, they form a generalization of a group called a higher Lie groupoid.
