Existence of a Hall ray in higher dimensional Lagrange spectra

Yitwah Cheung, Zhijing Wendy Wang, Ruichong Zhang

Given any norm $∥ \cdot ∥_{R^{2}}$ on $R^{2}$ , we prove that the Lagrange spectrum for $2$ -vectors contains a Hall ray. Equivalently, every sufficiently small $ρ \geq 0$ o…

Local centralizer rigidity for a non-generic diagonal map

Zhijing Wendy Wang, Amie Wilkinson

In this paper, we prove centralizer rigidity for any non-trivial diagonal map in the compact homogeneous space SL_n\mathbb{R}/Γ, n\ge 5, under the assumption that the perturbed vol…

Local centralizer rigidity for twisted Weyl chamber flows

Zhijing Wendy Wang

We prove local centralizer rigidity results for elements of Weyl chamber flows and twisted Weyl chamber flows on compact homogeneous spaces. For generic elements in the twisted set…
