Determination of $GL(3)$ Hecke-Maass forms from twisted central values

Ritabrata Munshi, Jyoti Sengupta

Suppose ${\pi }_1$ and ${\pi }_2$ are two Hecke-Maass cusp forms for $SL(3,\mathbb{Z})$ such that for all primitive character $\chi$ we have $$ L(\tfrac{1}{2},π_1\otimesχ)=L(\tfrac{1}{2},π_2\ot…
