[HTML][HTML] A generalization of Ramanujan's congruence to modular forms of prime level

R Gaba, AA Popa - Journal of Number Theory, 2018 - Elsevier
We prove congruences between cuspidal newforms and Eisenstein series of prime level,
which generalize Ramanujan's congruence. Such congruences were recently found by …

On the trace formula for Hecke operators on congruence subgroups

A Popa - Proceedings of the American Mathematical Society, 2018 - ams.org
We give a new, simple proof of the trace formula for Hecke operators on modular forms for
finite index subgroups of the modular group. The proof uses algebraic properties of certain …

An elementary proof of the Eichler–Selberg trace formula

AA Popa, D Zagier - Journal für die reine und angewandte …, 2020 - degruyter.com
We give a purely algebraic proof of the trace formula for Hecke operators on modular forms
for the full modular group SL 2⁢(ℤ), using the action of Hecke operators on the space of …

A trace formula for Hecke operators on Fuchsian groups

AA Popa - arXiv preprint arXiv:2306.10396, 2023 - arxiv.org
In this paper we give a trace formula for Hecke operators acting on the cohomology of a
Fuchsian group of finite covolume, with coefficients in a module $ V $. The proof is based on …

On the trace formula for Hecke operators on congruence subgroups, II

AA Popa - Research in the Mathematical Sciences, 2018 - Springer
In a previous paper, we obtained a general trace formula for double coset operators acting
on modular forms for congruence subgroups, expressed as a sum over conjugacy classes …

Finite-dimensional period spaces for the spaces of cusp forms

D Choi, S Lim - Israel Journal of Mathematics, 2016 - Springer
Let k be a positive integer and P k⊂ C [X] the set of polynomials of degree less than or equal
to k. There exists an isomorphism, called the Eichler–Shimura isomorphism, between the …

A survey of the number theoretic properties of real analytic modular forms

J Drewitt - 2021 - eprints.nottingham.ac.uk
The purpose of this thesis is to study the number theoretic properties of real analytic modular
forms, which were recently introduced by F. Brown. We begin with a brief review of the …
