Fourier-Jacobi Expansion of Eisenstein Series on Unitary Groups of Degree Three
After reformulating Shintani's theory of Fourier- Jacobi expansion of automorphic forms on $\,U(2,1)\,$ in the adelic setting, we show that the primitive components of holomorphic Eisenstein series are expressed in terms of the periods of primitive theta functions and critical values of Hecke $\,L$-functions.
