An algorithm to compute upper bounds of dimensions for Siegel Modular Forms of Prime Level and Arbitrary Nebentypus
Debargha Banerjee, Dron Airon, Pranjal Vishwakarma +1
We describe an algorithmic method to determine the image of restriction maps for Siegel modular forms with \textit{arbitrary} characters and arbitrary weight. A program has been im…

Two results on Eisenstein part of homology and cohomology groups of Bianchi modular groups
Debargha Banerjee, Pranjal Vishwakarma
We explicitly write down the {\it Eisenstein cycles} in the first homology groups of quotients of the hyperbolic three spaces as linear combinations of Cremona symbols (a generaliz…
