Triple product L-functions are the Langlands L-functions attached to a triple of automorphic representations of GL_{r_i} for positive integers r_1,r_2,r_3 and the tensor product representation GL_{r_1} \times GL_{r_2} \times GL_{r_3} \lto \GL_{r_1r_2r_3}.
If we knew their analytic properties then by the converse theorem one would be able to deduce the automorphy of Rankin-Selberg products of automorphic representations. This corresponds to the special case r_3=1. This in turn would make huge inroads into Langlands functoriality. I will report on joint work with Pam Gu, Chun-Hsien Hsu, and Spencer Leslie in which we construct an integral representation related to triple product L-functions, generalizing work of Garrett, Piatetski-Shapiro, and Rallis in the case r_1=r_2=r_3=2. I will also comment on the obstacles to using this integral representation to obtain the functional equation of triple product L-functions, and how one might overcome them.
