A construction of a connection on G Y Y from a connection on Y M by means of classical linear connections on M and Y

Włodzimierz M. Mikulski (2005)

Commentationes Mathematicae Universitatis Carolinae

Let G be a bundle functor of order ( r , s , q ) , s r q , on the category m , n of ( m , n ) -dimensional fibered manifolds and local fibered diffeomorphisms. Given a general connection Γ on an m , n -object Y M we construct a general connection 𝒢 ( Γ , λ , Λ ) on G Y Y be means of an auxiliary q -th order linear connection λ on M and an s -th order linear connection Λ on Y . Then we construct a general connection 𝒢 ( Γ , 1 , 2 ) on G Y Y by means of auxiliary classical linear connections 1 on M and 2 on Y . In the case G = J 1 we determine all general connections 𝒟 ( Γ , ) on J 1 Y Y from...

A generalization of the exterior product of differential forms combining Hom-valued forms

Christian Gross (1997)

Commentationes Mathematicae Universitatis Carolinae

This article deals with vector valued differential forms on C -manifolds. As a generalization of the exterior product, we introduce an operator that combines Hom ( s ( W ) , Z ) -valued forms with Hom ( s ( V ) , W ) -valued forms. We discuss the main properties of this operator such as (multi)linearity, associativity and its behavior under pullbacks, push-outs, exterior differentiation of forms, etc. Finally we present applications for Lie groups and fiber bundles.
