G-fibration

In algebraic topology, a G-fibration or principal fibration is a generalization of a principal G-bundle, just as a fibration is a generalization of a fiber bundle. By definition, given a topological monoid G, a G-fibration is a fibration p: P→B together with a continuous right monoid action P × G → P such that (1) p = p for all x in P and g in G.
(2) For each x in P, the map G → p − 1 , g ↦ x g is a weak equivalence. A principal G-bundle is a prototypical example of a G-fibration. Another exampl
