On Almost-Fuchsian Manifolds

, 2013
Almost-Fuchsian manifold is a class of complete hyperbolic three manifolds. Such a three-manifold is a quasi-Fuchsian manifold which contains a closed incompressible minimal surface with principal curvatures everywhere in the range of (-1, 1).

On 3-manifolds that support partially hyperbolic diffeomorphisms

, 2010
Let M be a closed 3-manifold that supports a partially hyperbolic diffeomorphism f. If $\pi_1(M)$ is nilpotent, the induced action of f on $H_1(M, R)$ is partially hyperbolic.

Dehn filling of the "magic" 3-manifold

, 2005
We classify all the non-hyperbolic Dehn fillings of the complement of the chain-link with 3 components, conjectured to be the smallest hyperbolic 3-manifold with 3 cusps. We deduce the classification of all non-hyperbolic Dehn fillings of infinitely many

Finite groups and hyperbolic manifolds [PDF]

Inventiones mathematicae, 2005
The isometry group of a compact n-dimensional hyperbolic manifold is known to be finite. We show that for every n > 2, every finite group is realized as the full isometry group of some compact hyperbolic n-manifold. The cases n = 2 and n = 3 have been proven by Greenberg and Kojima, respectively.

Curved momentum spaces from quantum groups with cosmological constant

Physics Letters B, 2017
We bring the concept that quantum symmetries describe theories with nontrivial momentum space properties one step further, looking at quantum symmetries of spacetime in presence of a nonvanishing cosmological constant Λ. In particular, the momentum space

Magnetically charged AdS 5 black holes from class S $$ \mathcal{S} $$ theories on hyperbolic 3-manifolds

Journal of High Energy Physics, 2020
We study the twisted index of 4d N $$ \mathcal{N} $$ = 2 class S $$ \mathcal{S} $$ theories on a closed hyperbolic 3-manifold M 3. Via 6d picture, the index can be written in terms of topological invariants called analytic torsions twisted by irreducible

Density of systoles of hyperbolic manifolds

Comptes Rendus. Mathématique
We show that for each $n \ge 2$, the systoles of closed hyperbolic $n$-manifolds form a dense subset of $(0, +\infty )$. We also show that for any $n\ge 2$ and any Salem number $\lambda $, there is a closed arithmetic hyperbolic $n$-manifold of systole $\

Stability boundary characterization of nonlinear autonomous dynamical systems in the presence of a type-zero saddle-node equilibrium point

Trends in Computational and Applied Mathematics, 2010
. Under the assumption that all equilibrium points are hyperbolic, the stability boundary of nonlinear autonomous dynamical systems is characterized as the union of the stable manifolds of equilibrium points on the stability boundary.
