Map whose fibers are homotopic/homeomorphic are is a fibration

132 Views Asked by At

Now I know that the fibers of a fibration are homotopy equivalent, but I was wondering if the converse was true if we have the stronger conidition that the fibers are homeomorphic. If a map whose fibers are homeomorphic do we have a fibration, and if we weaken it to just homotopy equivalent are there additional conditions we can give so that the map is a fibration.
