On the archimedean local gamma factors for adjoint representation of GL$_3$, part I

Vol. 304 (2020), No. 1, 303–345

Studying the analytic properties of the partial Langlands L-function via Rankin–Selberg method has proved to be successful in various cases. Yet in few cases is the local theory studied at the archimedean places, which causes a tremendous gap in the completion of the analytic theory of the complete L-function. We establish the meromorphic continuation and the functional equation of the archimedean local integrals associated with D. Ginzburg’s global integral (1991) for the adjoint representation of GL3. Via the local functional equation, the local gamma factor Γ(s,π,Ad,ψ) can be defined. In a forthcoming paper, we will compute the local gamma factor Γ(s,π,Ad,ψ) explicitly, which fill in some blanks in the archimedean local theory of Ginzburg’s global integral.
