  • Sign changes of coefficients of certain Dirichlet series 
    Meher, Jaban; PUJAHARI, SUDHIR; Shankhadhar, Karam Deo (Project Euclid, 2015-03)
    In this paper, we give criteria for infinitely many sign changes of the coefficients of any Dirichlet series if the coefficients are real numbers. We also provide examples where our criteria are applicable.
  • Automorphic tensor products and cuspidal cohomology of the GL(4) 
    BHAGWAT, CHANDRASHEEL; MONDAL, SUDIPA (World Scientific Publishing Co Pte Ltd, 2023-06)
    In this paper, we establish an asymptotic lower bound estimate on the contribution of cuspidal automorphic representations of GL4(AQ)GL4(𝔸ℚ) to cuspidal cohomology of the GL4GL4 which are obtained from automorphic tensor ...
