Euler-Kronecker constants of modular forms: beyond Dirichlet -series
Steven Charlton, Anna Medvedovsky, Pieter Moree
The Euler-Kronecker constants related to congruences of Fourier coefficients of modular forms that have been computed so far, involve logarithmic derivatives of Dirichlet -serie…
On the parity of coefficients of eta powers
Steven Charlton, Lukas Mauth, Anna Medvedovsky
We consider a special subsequence of the Fourier coefficients of powers of the Dedekind -function, analogous to the sequence on which exceptional…
Mod- Hecke algebras of level and
Shaunak V. Deo, Anna Medvedovsky
We use deformation theory to study the big Hecke algebra acting on mod-2 modular forms of prime level and all weights, especially its local component at the trivial representat…
Deep congruences + the Brauer-Nesbitt theorem
Samuele Anni, Alexandru Ghitza, Anna Medvedovsky
We prove that mod- congruences between polynomials in are equivalent to deeper -power congruences between power-sum functions of their roots. This result ge…
Big images of two-dimensional pseudorepresentations
Andrea Conti, Jaclyn Lang, Anna Medvedovsky
Bellaïche has recently applied Pink-Lie theory to prove that, under mild conditions, the image of a continuous 2-dimensional pseudorepresentation of a profinite group on a loca…
Newforms mod p in squarefree level, with applications to Monsky's Hecke-stable filtration
Shaunak V. Deo, Anna Medvedovsky, Alexandru Ghitza
We propose an algebraic definition of the space of l-new mod-p modular forms for Gamma0(Nl) in the case that l is prime to N, which naturally generalizes to a notion of newforms mo…
Mod-2 dihedral Galois representations of prime conductor
Kiran S. Kedlaya, Anna Medvedovsky
For all odd primes N up to 500000, we compute the action of the Hecke operator T_2 on the space S_2(Gamma_0(N), Q) and determine whether or not the reduction mod 2 (with respect to…
Nilpotence order growth of recursion operators in characteristic p
Anna Medvedovsky
We prove that the killing rate of certain degree-lowering "recursion operators" on a polynomial algebra over a finite field grows slower than linearly in the degree of the polynomi…
