Period relations for Rankin-Selberg convolutions for $\mathrm{GL}(n)\times \mathrm{GL}(n)$

Yubo Jin, Jian-Shu Li, Dongwen Liu +1

Using the modular symbol approach, we prove the rationality and period relations for certain critical values of Rankin-Selberg L-functions for $\mathrm{GL}(n)\times \mathrm{GL}(n)$…
