On abelian self-dual multimonopoles

Abelian self-dual monopoles are Dirac monopoles which also act as the source of a scalar field equal in strength to the potential of the magnetic field. The static field generated by several such monopoles with arbitrary positions can be described by adapting the ADHM formalism developed for instantons. In particular one obtains an exact expression for the Green function of the covariant Laplace operator. (orig.)
