Branches of differential geometry
... Finsler geometry has the Finsler manifold as the main object of study — this is a differential manifold with a Finsler metric, i.e. a Banach norm defined on each tangent space. A Finsler metric is a much more general structure than a Riemannian metric. A Finsler structure on a manifold M is a functi ...

LECTURE 30: INDUCED MAPS BETWEEN CLASSIFYING SPACES
... Suppose that α : G → H is a homomorphism of topological groups. We can get an induced map α∗ : BG → BH by providing a natural transformation between the functors that these spaces rep resent: α∗ : {Gbundles over X} → {Hbundles over X}. Namely, send a Gbundle E → X to the Hbundle H ×G E → X wher ...
