Webtwo 4-manifolds, fibered as above, are diffeomorphic, then there is a fiber preserving diffeomorphism between them which is orthogonal on fibers. Our interest in S2-bundles arose in the study of Lie group actions (in particular of S0(3)) on 4-manifolds. The results obtained here are used in the equivariant classification of such actions [MP]. 1. WebglX x bdy a to the embedding g I X x {s}.

WebYou can find an easy bijection $TM\leftrightarrow M\times\mathbb {R}^n$, but you cannot in general find a fiber-preserving diffeomorphism between the two spaces. When we trivialize, we require that $F:TM\to M\times V$ be not just a diffeomorphism but a diffeomorphism that is a fiberwise isomorphism.

Webfiber-preserving diffeomorphism [BO]. So, any orientation preserving self-diffeomorphism is isotopic to the identity, or to an involution that reverses the orientation of both base and fiber.
