On Deligne's Conjecture for Certain Automorphic $L$-Functions for $\mathrm{GL}(3)\times\mathrm{GL}(2)$ and $\mathrm{GL}(4)$
Documenta mathematica, Tome 24 (2019), pp. 2241-2297
We prove Deligne's conjecture for certain automorphic L-functions for GL(3)×GL(2) and GL(4). The proof is based on rationality results for central critical values of triple product L-functions, which follow from establishing explicit Ichino's formulae for trilinear period integrals for Hilbert cusp forms on totally real étale cubic algebras over Q.
