Query: A metric deformation on fiber bundles and applications   We develop the concept of a Cheeger deformation on the context of fiber
bundles with compact structure group. This procedure is used to provide metrics
with positive Ricci curvature on the total space of such bundles, generalizing
the results in Nash \cite{nash1979positive} and Poor \cite{poor1975some}.
