On Lower Bounds for sums of Fourier Coefficients of Twist-Inequivalent Newforms

Moni Kumari, Prabhat Kumar Mishra, Jyotirmoy Sengupta

In this article, we address the lower bounds for the sums $a_{f} (p) + a_{g} (p)$ of the $p$ -th Fourier coefficients of two twist-inequivalent, non-CM normalized newforms $f$ and $g$ . Our…

Sign changes of Fourier coefficients of Siegel cusp forms of degree two on Hecke congruence subgroups

S. Gun, J. Sengupta

In this article, the authors give a lower bound on the number of sign changes of Fourier coefficients of a non-zero degree two Siegel cusp form of even integral weight on a Hecke c…

Determination of $G L (3)$ Hecke-Maass forms from twisted central values

Ritabrata Munshi, Jyoti Sengupta

Suppose $π_{1}$ and $π_{2}$ are two Hecke-Maass cusp forms for $S L (3, Z)$ such that for all primitive character $χ$ we have $$ L(\tfrac{1}{2},π_1\otimesχ)=L(\tfrac{1}{2},π_2\ot…
