Let M be a 3-dimensional compact manifold with non-empty boundary. There exists a collection of tetrahedra stuck in pairs along their faces such that deleting all their vertices gives a space that is homeomorphic to the interior of M. This is called a (ideal) triangulation of M. Amendola, Matveev and Piergallini have shown that any two such triangulations of M are connected by a sequence of triangulations, where each triangulation in the sequence is obtained from the previous one by a local combinatorial change, namely a 2-3 or 3-2 move.

Number theory lunch seminar

Though the number $\pi$ is known to be irrational and transcendental, there are still a lot of open (and non-approachable at the moment) questions about its approximations by rational numbers. Where do such difficulties source from? What is exactly proving that a given (nice) number is irrational? How relevant is the structure of such concrete irrationality proofs? In my talk I will try to highlight these points and to explain why the "structure" is most important, in particular, when it comes to connection with more rational areas in mathematics.

Constructing modular forms geometrically

Modular forms live on moduli spaces of abelian varieties and curves as sections of vector bundles. We indicate
geometric ways of constructing such forms.

This is joint work with Cléry, Faber and Kouvidakis.

On the Homological Theory of Modules over Commutative Rings

Parent event: 
MPI-Oberseminar

This talk will be a partial survey of topics in homological commutative local algebra. In particular, I will discuss results on depth, homological dimensions, and torsion properties of tensor products and powers, as well as characterizations of Gorenstein and regular rings via (co)homology vanishing. I will also mention related conjectures and open problems in this area.
