Generating the Johnson filtration
Thomas Church, Andrew Putman
For k >= 1, let Torelli_g^1(k) be the k-th term in the Johnson filtration of the mapping class group of a genus g surface with one boundary component. We prove that for all k, ther…
Representation stability in cohomology and asymptotics for families of varieties over finite fields
Thomas Church, Jordan S. Ellenberg, Benson Farb
We consider two families X_n of varieties on which the symmetric group S_n acts: the configuration space of n points in C and the space of n linearly independent lines in C^n. Give…
Rotor-routing and spanning trees on planar graphs
Melody Chan, Thomas Church, Joshua A. Grochow
The sandpile group Pic^0(G) of a finite graph G is a discrete analogue of the Jacobian of a Riemann surface which was rediscovered several times in the contexts of arithmetic geome…
