April 18, 2024 10:15 amWhat is the smallest genus h of a non-isotrivial curve over the generic genus g curve? In joint work with Daniel Litt, we show h is more than $\sqrt{g}$ by...

CMSA GENERAL RELATIVITY SEMINAR, CMSA EVENTS
April 16, 2024 11:00 amWe consider four-dimensional Euclidean gravity in a finite cavity. We point out that there exists a one-parameter family of boundary conditions, parameterized by a real constant, where a suitably Weyl-rescaled...

April 12, 2024 12:00 pmIt is important to understand if the `solutions' of non-linear evolutionary PDEs persist for all time or become extinct in finite time through the blow-up of invariant entities. Now the...

April 11, 2024 10:30 amIn 2016, Doran, Harder, and I conjectured a mirror symmetric relationship between Tyurin degenerations and splittings of codimension 1 fibrations on Calabi-Yau manifolds. In this talk I will discuss recent...
