Tomter's example revisited
Danyu Zhang
We construct examples of fibrewise Anosov flows over the Fenley--Mann--Potrie example of dimension 4. This is a family of non-algebraic Anosov flows with unstable dimension …

An obstruction to fiberwise Anosov flows over 3-dimensional Anosov flows
Neige Paulet, Danyu Zhang
We study obstructions preventing a three-dimensional Anosov flow from serving as the base of a fiberwise Anosov flow. We prove a non-existence result if the base flow admits infini…
