Query: Fermion Zero Modes for Abelian BPS Monopoles   Fermion zero modes for abelian BPS monopoles are considered. In the
spherically symmetric case the normalisable zero modes are determined for
arbitrary monopole charge N. If N>1 the zero modes are zero along $N-1$
half-lines emanating from the monopole.
