Multiplicativity in fibre bundles,The Milnor manifolds H. ⊂ ℙ. × ℙ. of the last section are total spaces of a beautiful fibre bundle. To see this, we consider the projection of ℙ. × ℙ., onto ℙ.. This induces for . ≤ . a fibration of .. over ℙ. with fibre ℙ., as one sees directly from the equation for H.. The manifold .. is therefore the total space of a projective bundle over ℙ..

The Atiyah-Singer index theorem,tor space of all ..-sections of a bundle, and let .: Г(.) + Г(.) be a ℂ-linear map. Each . ∈ Г(.) can be written over a trivializing neighborhood . of a point . ∈ . as . = (..,..., ..), where the .. are C.-functions over .. In the same way the image . = .(.) can be written locally as . = (..,..., ..
