On Jiang's Bounded Index Property for products of nilmanifolds
Peng Wang, Qiang Zhang, Xuezhi Zhao
In 2023, Zhang and Zhao presented the first examples of aspherical manifolds lacking the Bounded Index Property (BIP) for fixed points. This answered a question posed by Jiang in 1…

Classification of aut-fixed subgroups in free-abelian times surface groups
Jialin Lei, Peng Wang, Qiang Zhang
In this paper, we are concerned with the direct product for a compact orientable surface with negative Euler characteristic, and give a complete classi…

Iwip endomorphisms of free groups and fixed points of graph selfmaps
Peng Wang, Qiang Zhang
In a paper from 2011, Jiang, Wang and Zhang studied the fixed points and fixed subgroups of selfmaps on a connected finite graph or a connected compact hyperbolic surface . In p…
