Recovering modular forms and representations from tensor and symmetric powers

C. S. Rajan

We consider the problem of determining the relationship between two representations knowing that some tensor or symmetric power of the original represetations coincide. Combined wi…

Distinguished representations, base change, and reducibility for unitary groups

U. K. Anandavardhanan, C. S. Rajan

We show the equality of the local Asai L-functions defined via the Rankin-Selberg method and the Langlands-Shahidi method for a square integrable representation of GL(n,E). As a co…

On strong multiplicity one for automorphic representations

C. S. Rajan

We extend the strong multiplicity one theorem of Jacquet, Piatetski-Shapiro and Shalika. Let be a unitary, cuspidal, automorphic representation of $GL_n(\A_K)$. Let be a se…

On Langlands functoriality- reduction to the semistable case

C. S. Rajan

We generalize a beautiful method of Blasius and Ramakrishnan, that in order to exhibit particular instances of the Langlands functorial correspondence, it is enough to show that th…

On the vanishing of the measurable Schur cohomology groups of Weil groups

C. S. Rajan

We generalize a theorem of Tate and show that the second cohomology of the Weil group of a global or local field with coefficients in $\C^*$ (or more generally, with coefficients i…

Recovering l-adic representations

C. S. Rajan

We consider the problem of recovering l-adic representations from a knowledge of the character values at the Frobenius elements associated to l-adic representations constructed alg…
