Simultaneous behaviour of the Fourier coefficients of two Hilbert modular cusp forms
Surjeet Kaushik, Narasimha Kumar
In this article, we study the simultaneous sign changes of the Fourier coefficients of two Hilbert cusp forms of different integral weights. We also study the simultaneous non-vani…

Equidistribution of signs for Hilbert modular forms of half-integral weight
Surjeet Kaushik, Narasimha Kumar, Naomi Tanabe
We prove an equidistribution of signs for the Fourier coefficients of Hilbert modular forms of half-integral weight. Our study focuses on certain subfamilies of coefficients that a…

Surjeet Kaushik, Narasimha Kumar
Suppose is an elliptic curve over of conductor with complex multiplication (CM) by , and is the corresponding cuspidal Hecke eigenform in…
