Query: Eisenstein series with non-unitary twists   It is shown that for a non-unitary twist of a Fuchsian group, which is
unitary at the cusps, Eisenstein series converge in some half-plane. It is
shown that invariant integral operators provide a spectral decomposition of the
space of cusp forms and that Eisenstein series admit a meromorphic
continuation.
