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…

A 2-adic control theorem for modular curves
Narasimha Kumar
We study the behaviour of ordinary parts of the homology modules of modular curves, associated to a decreasing sequence of congruence subgroups for , and prov…
