John A. Baldwin (Boston College)

We prove that the 3-manifold obtained by gluing the complements of two nontrivial knots in homology 3-sphere instanton L-spaces, by a map which identifies meridians with Seifert longitudes, cannot be an instanton L-space. This recovers the recent theorem of Lidman–Pinzon-Caicedo–Zentner that the…

I will describe the use of ensemble based particle methods to solve inverse problems, including ensemble and unscented Kalman methods. I will show how multiscale analysis can be used to understand the performance of these methods; and I will show how multiscale methods can be used to improve…

Remy van Dobben de Bruyn (Princeton/IAS)

The inverse Hodge problem asks which possible Hodge diamonds can occur for smooth projective varieties. While this is a very hard problem in general, Paulsen and Schreieder recently showed that in characteristic 0 there are no restrictions on the modulo m Hodge numbers, besides the usual…
