Rare Earth Elements, Alloys and CompoundsIn this chapter we will first give several equivalent constructions of a connection on a principal bundle, and then generalize the notion curvature to a principal bundle, paving the way to a generalization of characteristic classes to principal bundles. Along the way, we also generalize covariant derivatives to principal bundles.

Introduction to rare earth elements,.. manifolds (., .) with a marked point to the category of vector spaces. Much of differential topology and differential geometry consists of trying to see how much of the geometric information is encoded in the linear algebra of tangent spaces. To this end, we need a larger arsenal of algebraic tec

Rare Earth Elements, Alloys and Compoundsection .. These forms turn out to be closed; moreover, their cohomology classes are independent of the connection and so are diffeomorphism invariants of the vector bundle .. They are called . of .. Specializing to the tangent bundle ., we obtain in this way new diffeomorphism invariants of the mani
