Pandemic Pulse: Unraveling and Modeling Social Signals during the COVID-19 Pandemic
Steven J. Krieg, Jennifer J. Schnur, Jermaine D. Marshall +2
We present and begin to explore a collection of social data that represents part of the COVID-19 pandemic's effects on the United States. This data is collected from a range of sou…
From partitions to Hodge numbers of Hilbert Schemes of Surfaces
Nate Gillman, Xavier Gonzalez, Ken Ono +2
We celebrate the 100th anniversary of Srinivasa Ramanujan's election as a Fellow of the Royal Society, which was largely based on his work with G. H. Hardy on the asymptotic proper…
Exact Formulas for Invariants of Hilbert Schemes
Nate Gillman, Xavier Gonzalez, Matthew Schoenbauer
A theorem of Göttsche establishes a connection between cohomological invariants of a complex projective surface and corresponding invariants of the Hilbert scheme of points…
Relating Cut and Paste Invariants and TQFTs
Carmen Rovi, Matthew Schoenbauer
In this paper, we shall be concerned with a relation between TQFTs and cut and paste invariants introduced by Karras, Kreck, Neumann and Ossa. Cut and paste invariants, or SK invar…
