Jds. Jones et Mk. Murray, A NOTE ON THE INDEX BUNDLE OVER THE MODULI SPACE OF MONOPOLES, Communications in Mathematical Physics, 170(2), 1995, pp. 445-451
Donaldson has shown that the moduli space of monopoles M(k) is diffeom
orphic to the space Rat(k) of based rational maps from the two-sphere
to itself. We use this diffeomorphism to give an explicit description
of the bundle on Rat(k) obtained by pushing out the index bundle from
M(k). This gives an alternative and more explicit proof of some earlie
r results of Cohen and Jones.
