Homomorphisms of Topological Groups which are Automatically Fiber Bundles?
The following statement follows from results of Palais (see theorem 2.3.3 in "On the existence of slices for actions of non-compact Lie groups"). When $G$ is a Lie group, any principal $G$-bundle (in …

Homotopy Equivalences and Induced Correspondences between Fibre Bundles
Here is a quick argument which proves homotopy equivalence directly. First, the pullback of a homotopy equivalence along a Hurewicz fibration is again a homotopy equivalence. Further, by the well-know …
