We will show an identity between an orthogonal period of a minimal
parabolic Eisenstein series on GL(3) and Whittaker coefficients of an
Eisenstein series on the metaplectic double cover of GL(3), thereby
providing evidence in favor of a conjecture of Jacquet. The main tool
used in the proof is Gauss's three squares theorem. This is joint work
with O. Offen.
