Abstract

We extend the definition of the topological charge pertaining to the CP1 (i.e. O(3)) Skyrme-Fadde’ev Hopfion on IR3, to candidates for topological charges of CPn sigma models on IR2n+1, for all n. For this, the Abelian composite connections of the CPn sigma models are employed. In higher dimensions (n ≥ 1) it turns out that such charges, described by the non- Abelian composite connections of suitable Grassmannian sigma models, can also be constructed. A concrete discussion of the non-Abelian case for n = 2 is presented.
