Z_N-Higgs Models.

ABSTRACT.  We construct dyonic states in 2+1-dimensional lattice Z_N-Higgs
models, i.e., states which are both, electrically and magnetically
charged.  The associated Hilbert spaces carry charged representations
of the observable algebra, the global transfer matrix and a unitary
implementation of the group of spatial lattice translations. We prove
that for coinciding total charges these representations are
dynamically equivalent and we construct a local intertwiner connection
depending on a path in the space of charge distributions.  The
holonomy of this connection is given by Z_N-valued phases.  This will
be the starting point for a construction of scattering states with
anyon statistics in a subsequent paper.
