      I am a postdoc at University of Luxembourg since September 2023, under the supervision of Karin Melnick.

      I received my PhD in Math in May 2023, from The Ohio State University where my thesis advisor was Andrey Gogolev.

      My name in simplified Chinese: 张丹彧.

Research

      I am broadly interested in questions with a flavor of understanding the underlying topology and / or geomerty of the spaces with the presence of dynamics (or maybe vice versa).

Papers and preprints

1. Anosov diffeomorphisms on a product of surfaces (2022). arXiv, updated pdf. Submitted.
2. Structural stability for fibrewise Anosov diffeomorphisms on principal torus bundles (2021). Ergodic Theory and Dynamical Systems. 2024;44(1):334-352. arXiv.

In progress

1. New examples of Anosov flows on higher dimensional manifolds which fibre over 3-dimensional Anosov flows (2022). arXiv. (Caution: there’s a mistake. I’d be very happy to chat about this.)
