Lacunary recurrences and 2-adic properties of Eisenstein series

Liubomir Chiriac, Andrei Jorza

We study the rational coefficients that arise when the Eisenstein series $G_{k}$ is expressed as a polynomial in $G_{4}$ and $G_{6}$ , proving a conjecture that gives an exact formula for…

The variation of zeros of the Miller basis

Liubomir Chiriac, Andrei Jorza

We exhibit a connection between the variation of zeros in the Miller basis of modular forms $q^{m} + O (q^{ℓ + 1})$ and a logarithmic version $S_{δ}$ of the Szegő curve, where…

Parahoric level $p$ -adic $L$ -functions for automorphic representations of $GL_{2 n}$ with Shalika models

Mladen Dimitrov, Andrei Jorza

We construct $p$ -adic $L$ -functions for regularly refined cuspidal automorphic representations of symplectic type on $GL_{2 n}$ over totally real fields, which are pa…
