Given a bundle whose base space is a "cylinder", i.e. $\mathbb{S}^1 \times \mathbb{B}^n$ where $\mathbb{B}^n$ is an $n$-ball, is orientability (of the total space) enough to ensure that the bundle is trivial, and how does one go about showing this.
I would basically like to understand the next simplest case after that of bundles with contractible base space, which are all trivial.
It feels like there should be a simple answer, that doesn't involve the diffoemorphism class of the fibres, possibly using some homotopy-type argument to reduce the question to a bundle with base space $\mathbb{S}^1$.
Also, are there any good references I should be looking at?
Thanks!
Steenrod's Topology of fiber bundles is indeed the place to look - thanks Ted Shifrin for the suggestion.
Theorem 11.4: If $X$ is a $C_\sigma$-space [normal and locally compact], then any bundle $\mathcal{B}'$ over the base space $X \times \mathbb{B}^1$ is equivalent to a bundle of the form $\mathcal{B} \times \mathbb{B}^1$.
So my question reduces to the same question for a bundle over a circle, and then one can find examples of orientable non-trivial bundles.
