Remarks on the Dijkgraaf-Witten invariants of 3D mapping tori
William Chen, Alex Kontorovich, Shehryar Sikander
We make some remarks on the Dijkgraaf-Witten invariants of 3D mapping tori and determine the asymptotic behavior of their sum over all diffeomorphism classes of genu…
Nonabelian level structures, Nielsen equivalence, and Markoff triples
William Chen
In this paper we establish a congruence on the degree of the map from a component of a Hurwitz space of covers of elliptic curves to the moduli stack of elliptic curves. Combinator…
Tamely Ramified Covers of the Projective Line with Alternating and Symmetric Monodromy
Renee Bell, Jeremy Booher, William Y. Chen +1
Let be an algebraically closed field of characteristic and let the projective line over with three points removed. We investigate which finite groups can arise…
Cardinal characteristics of the continuum and partitions
William Chen, Shimon Garti, Thilo Weinert
We prove combinatorial theorems concerning the stick principle and cardinal characteristics.
Arithmetic monodromy actions on pro-metabelian fundamental groups of once-punctured elliptic curves
William Yun Chen, Pierre Deligne
We prove structure theorems for the moduli stack of elliptic curves equipped with -structures, where is a finite 2-generated metabelian group. In particular, we show that if…
Nilpotency in instanton homology, and the framed instanton homology of a surface times a circle
William Chen, Christopher Scaduto
In the description of the instanton Floer homology of a surface times a circle due to Muñoz, we compute the nilpotency degree of the endomorphism . We then compute the fram…
