The Prasad conjectures for $\mathrm{GSp_4}$ and $\mathrm{PGSp_4}$

Abstract

In this paper, we use the theta correspondence between GSp4\mathrm{GSp_4} and GO(V)\mathrm{GO(V)} to discuss the GSp4\mathrm{GSp_4}-distinction problems over a quadratic field extension E/F.E/F. With a similar strategy, we study the period for the pair (GSp4(E),GSp1,1(F)),(\mathrm{GSp_4(E)},\mathrm{GSp_{1,1}(F)}), where GSp1,1\mathrm{GSp_{1,1}} is the unique inner form of GSp4.\mathrm{GSp_4}. Then we verify the Prasad conjecture for PGSp4(E)\mathrm{PGSp_4(E)}.

We extend the results from tempered representations in the previous version (v1) to the generic representations. arXiv admin note: text overlap with arXiv:0706.0952 by other authors
