Abstract

In the spirit of noncommutative geometry we construct all inequivalent vector bundles over the (2,2)(2,2)-dimensional supersphere S2,2S^{2,2} by means of global projectors pp via equivariant maps. Each projector determines the projective module of finite type of sections of the corresponding `rank 1' supervector bundle over S2,2S^{2,2}. The canonical connection =pd\nabla = p \circ d is used to compute the Chern numbers by means of the Berezin integral on S2,2S^{2,2}. The associated connection 1-forms are graded extensions of monopoles with not trivial topological charge. Supertransposed projectors gives opposite values for the charges. We also comment on the KK-theory of S2,2S^{2,2}.
