Abstract:

Let $\pi _i$ be an irreducible cuspidal automorphic representation of $\mathrm {GL}_2$ with central character $\omega _i$. When $\omega _1\omega _2\omega _3$ is trivial, Atsushi Ichino proved a formula for the central value $L(\frac {1}{2}, \pi _1\times \pi _2\times \pi _3)$ of the triple product $L$-series in terms of global trilinear forms. We will extend this formula to the case when $\omega _1\omega _2\omega _3$ is a quadratic character, giving a non-vanishing criterion of a local trilinear form in terms of the central value of the gamma factor.
