Angular momentum in general relativity

DIFFERENTIAL GEOMETRY

May 12, 2020      3:00 pm
Speaker: Mu-Tao Wang - Columbia University

In the theory of general relativity, defining a valid notion of angular momentum is proven to be an even more challenging task than the definition of energy/mass. In this talk,...

Gauge theory for string algebroids

DIFFERENTIAL GEOMETRY

May 7, 2020      4:00 pm
Speaker: Mario Garcia-Fernandez - ICMAT

We introduce a moment map picture for holomorphic string algebroids, a special class of holomorphic Courant algebroids introduced in arXiv:1807.10329. An interesting feature of our construction is that the Hamiltonian...

Weak SYZ conjecture for hypersurfaces in the Fermat family

DIFFERENTIAL GEOMETRY

April 28, 2020      3:00 pm
Speaker: Yang Li - Institute for Advanced Study

The SYZ conjecture predicts that for polarised Calabi-Yau manifolds undergoing the large complex structure limit, there should be a special Lagrangian torus fibration. A weak version asks if this fibration...

Unknottedness of noncompact self shrinkers

DIFFERENTIAL GEOMETRY

April 21, 2020      3:00 pm
Speaker: Alex Mramor - Johns Hopkins University

In this talk I’ll discuss work in preparation on the unknottedness of asymptotically conical self shrinkers in R^3. via Zoom Video Conferencing: if you would like to attend, please email...

Collapsing Calabi-Yau Manifolds

DIFFERENTIAL GEOMETRY

April 7, 2020      4:15 pm
Speaker: Valentino Tosatti - Northwestern University

via Zoom Video Conferencing:  link TBA I will report on some recent progress on the problem of understanding the collapsing behavior of Ricci-flat Kahler metrics on Calabi-Yau manifolds that admit...

Dynamical Black Hole Formation

DIFFERENTIAL GEOMETRY

February 18, 2020      4:15 pm
Speaker: Martin Lesourd - Harvard University, CMSA

In 2008, Christodoulou achieved a major breakthrough in the context of mathematical general relativity in being able to form trapped surfaces dynamically from initial data for the Einstein vacuum system....
