On the Dimension of Cohomology of Bianchi Groups
Mehmet Haluk Sengun, Seyfi Turkelli
Using Lefschetz numbers of certain involutions, we provide lower bounds for the cuspidal cohomology of principal congruence subgroups of Bianchi groups. The asymptotic lower bounds…
Connected Components of Hurwitz Schemes and Malle's Conjecture
Seyfi Turkelli
Let Z(X) be the number of degree-d extensions of F_q(t) with bounded discriminant and some specified Galois group. The problem of computing Z(X) can be related to a problem of coun…
Counting Multisections in Conic Bundles over a Curve defined over F_q
Seyfi Turkelli
For a given conic bundle X over a curve C defined over F_q, we count irreducible branch covers of C in X of degree d and height e>>1. As a special case, we get the number of algebr…
Weight Reduction for Mod l Bianchi Modular Forms
Mehmet Haluk Sengun, Seyfi Turkelli
Let K be an imaginary quadratic field with class number one and ring of integers O. We prove that mod l, a system of Hecke eigenvalues occurring in the first cohomology group of so…
