We extend the relation between instanton and monopole solutions of the selfduality equations in SU (2) gauge theory to noncommutative space-times. Using this approach we construct a noncommutative version of the Wu-Yang monopole satisfying the selfduality (Bogomol'nyi) equations in noncommutative U (2) Yang-Mills-Higgs theory.

Coupling constant renormalization is investigated in 2 dimensional σ models related by non Abelian duality transformations. In this respect it is shown that already in the one loop order of perturbation theory the duals of a one parameter family of models, interpolating between the SU (2) principal model and the O(3) sigma model, behave differently from the original models. In particular we fin...

We consider the Einstein-Yang-Mills-Higgs equations for an SU(3) gauge group in a spherically symmetric ansatz. Several properties of the gravitating monopole solutions are obtained an compared with their SU(2) counterpart.
