A simple proof of the Eichler-Selberg trace formula
Alexandru A. Popa, Don Zagier
We give a short proof of the trace formula for Hecke operators on modular forms for the modular group, using the action of Hecke operators on the space of period polynomials.

Fully polynomial FPT algorithms for some classes of bounded clique-width graphs
David Coudert, Guillaume Ducoffe, Alexandru Popa
Parameterized complexity theory has enabled a refined classification of the difficulty of NP-hard optimization problems on graphs with respect to key structural properties, and so…

On the trace formula for Hecke operators on congruence subgroups, II
Alexandru A. Popa
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. Her…
