Description : In the original form given by Blaschke in the 1930s, the famous Principal Kinematic Formula expresses the Euler characteristic of the intersection of two sufficiently regular objects in euclidean space, integrated over the space of all possible relative positions, in terms of geometric invariants ...

Canal-U
Description : With Robert Haraway, Robert Meyerhoff, Nathaniel Thurston and Andrew Yarmola. We address the following question. What are all the 1-cusped hyperbolic 3-manifolds whose maximal cusps have low volume?  Among other things we will outline a proof that the figure-8 knot complement and its sister are ...

Canal-U
Description : The aim of these lectures is to give an introduction to quantum field theory on curved spacetimes, from the point of view of partial differential equations and microlocal analysis. I will concentrate on free fields and quasi-free states, and say very little on interacting fields or perturbative ...

Description : The fundamental problem in the theory of Diophantine approximation is to understand how well points in the Euclidean space can be approximated by rational vectors with given bounds on denominators. It turns out that Diophantine properties of points can be encoded using flows on homogeneous ...

Description : After recalling some features (and the value of) the invariant ``Ricci calculus'' of pseudo-­?Riemannian geometry, we look at conformal rescaling from an elementary perspective. The idea of conformal covariance is visited ...
