Cohomology of congruence subgroups of SL_3(Z), Steinberg modules, and real quadratic fields
Avner Ash, Dan Yasaki
We investigate the homology of a congruence subgroup Gamma of SL_3(Z) with coefficients in the Steinberg modules St(Q^3) and St(E^3), where E is a real quadratic field and the coef…

Perfect Forms over Imaginary Quadratic Fields
Kristen Scheckelhoff, Kalani Thalagoda, Dan Yasaki
In this work, we compute the perfect forms for all imaginary quadratic fields of absolute discriminant up to and study the number and types of the polytopes that arise. We p…
