The development of set theory in the 20th century was like the invention of a "mathematical telescope", through which we can observe all kinds of infinite sets and their interactions. In quite the opposite direction, bounded arithmetic serves as a...

Abstract: Neutron stars and black holes represent the inevitable endpoints of stellar evolution for high-mass stars. Despite the apparent fine-tuning of the physical conditions necessary to produce them, neutron stars are abundant in the Galaxy. On...

The study of descriptive set theory in the context of determinacy axioms began nearly 60 years ago. The context for this study is now understood to be the Axiom AD+, which is a refinement of the Axiom of Determinacy (AD).  The objects of this study...

I will discuss compatibility of the canonical $G$-valued $l$-adic local systems on Shimura varieties of non-abelian type $G$. In previous work with Klevdal, we settled this for the projections of the local systems to the adjoint group of $G$, and...

This semester, we will be beginning a *very informal* get-together every Monday of people interested in/working on phenomenology and new theories beyond the standard model.  The idea is to discuss over lunch, perhaps meet up around 12.20, grab lunch...
