An algebraic property of Hecke operators and two indefinite theta series

Vicentiu Pasol, Alexandru A. Popa

We prove an algebraic property of the elements defining Hecke operators on period polynomials associated with modular forms, which implies that the pairing on period polynomials co…

On the Petersson scalar product of arbitrary modular forms

Vicentiu Pasol, Alexandru A. Popa

We consider a natural extension of the Petersson scalar product to the entire space of modular forms of integral weight $k \geq 2$ for a finite index subgroup of the modular group. W…
