Query: Exact Zero-Modes of the Compact QED Dirac Operator   We calculate the low-lying eigenmodes of the Neuberger overlap-Dirac operator
for $4d$ compact lattice QED in the quenched approximation. In the strong
coupling phase we find exact zero-modes, quite similar as in non-Abelian
lattice QCD. Subsequently we make an attempt to identify responsible
topological excitations of the U(1) lattice gauge theory.
