  We analyze the frustrated Heisenberg antiferromagnet defined on a honeycomb
lattice using a Schwinger-boson mean-field theory. The spin-wave velocity and
the susceptibility are presented as functions of the strength of the
frustrating interaction for spin S=1/2, and the dynamic structure factor is
calculated for various temperatures and frustrations. For large S, we find an
increased Neel stability with respect to the classical case.
