 On the Modularity of the GL_2twisted Spinor Lfunction 
 Abstract:
There are famous theorems on the modularity of Dirichlet series
with Euler product attached to geometric or arithmetic objects. There is
Hecke's converse theorem, Wiles proof of the TaniyamaShimura conjecture,
and Fermat's Last Theorem to name a few. In this talk in the spirit of the
Langlands philosophy we raise the question on the modularity of the
GL_2twisted spinor Lfunction L(s,G \otimes h) related to automorphic forms G,
h on the symplectic group with similitues GSp(4) of degree 2 and GL_2.
This leads to several promising results and finally culminates into a
precise very general conjecture. This gives new insides into the Miyawaki
conjecture on spinor Lfunctions of modular forms. We indicate how this
topic is related to Ramakrishnan's work on the modularity of the RankinSelberg
Lseries.
