On reflections of congruence hyperbolic manifolds
Sami Douba, Franco Vargas Pallete
We show that the standard method for constructing closed hyperbolic manifolds of arbitrary dimension possessing reflective symmetries typically produces reflections whose fixed poi…
Ping-pong in the projective plane over a nonarchimedean field
Sami Douba, Dmitry Kubrak, Konstantinos Tsouvalas
We show that any lattice in , where is a nonarchimedean local field, contains an undistorted subgroup isomorphic to the free product …
Zariski-Closures of Linear Reflection Groups
Jacques Audibert, Sami Douba, Gye-Seon Lee +1
We give necessary and sufficient conditions for a linear reflection group in the sense of Vinberg to be Zariski-dense in the ambient projective general linear group. As an applicat…
Convex cocompact groups in real hyperbolic spaces with limit set a Pontryagin sphere
Sami Douba, Gye-Seon Lee, Ludovic Marquis +1
We exhibit two examples of convex cocompact subgroups of the isometry groups of real hyperbolic spaces with limit set a Pontryagin sphere: one generated by reflections of $\ma…
