# Rankin-Selberg Convolutions for \(\mathrm{SO}_{2ℓ+1}×\mathrm{GL}_{n}\) : Local Theory

Share this page
*David Soudry*

This work studies the local theory for certain Rankin-Selberg convolutions for the standard \(L\)-function of degree \(2\ell n\) of generic representations of \(\mathrm{ SO}_{2\ell +1}(F)\times \mathrm{GL}_n(F)\) over a local field \(F\). The local integrals converge in a half-plane and continue meromorphically to the whole plane. One main result is the existence of local gamma and \(L\)-factors. The gamma factor is obtained as a proportionality factor of a functional equation satisfied by the local integrals. In addition, Soudry establishes the multiplicativity of the gamma factor (\(\ell < n\), first variable). A special case of this result yields the unramified computation and involves a new idea not presented before. This presentation, which contains detailed proofs of the results, is useful to specialists in automorphic forms, representation theory, and \(L\)-functions, as well as to those in other areas who wish to apply these results or use them in other cases.
