课程描述 Description

The Teichmuller space of all negatively curved metrics for a high dimensional closed manifold M is defined to be the quotient of the space of all negatively curved metrics on M by the group of all self-diffeomorphisms of M which are homotopic to the identity. Different from the 2 dimensional case, these Teichmuller spaces for higher dimensional manifolds are not contractible in general. This course is aim at introducing the homotopy theory for Teichmuller spaces of negatively curved metrics on high dimensional manifolds and some related open problems.

  • Moduli Spaces of Positive Curvature Metrics

    Abstract:Besides the space of positive scalar curvature metrics, various moduli spaces have gained a lot of attention. Among those, the observer moduli space arguably has the best behaviour from a homotopy-theoretical perspective because the subgroup of observer diffeomorphisms acts freely on the space of Riemannian metrics if the underlying manifold is connected.In this talk, I will present ho...

  • QFT in curved spacetime II

    AbstractIn the first talk I plan to talk some aspects of classical and quantum information theory to introduce some entropies and their properties, then talk about algebraic formulation of qft (Haag Kastler framework) and ends with Casini's interpretation of Bekenstein bound. In the second talk I plan to revisit a bit of null Ryachaudhuri equation , area theorem and then talk about Wall's proof...
