Multiple Closed Geodesics on Positively Curved Finsler Manifolds

Advanced Nonlinear Studies, 2019
In this paper, we prove that on every Finsler manifold (M,F){(M,F)} with reversibility λ and flag curvature K satisfying (λλ+1 ...

Rotating black hole entropy from M5-branes

Journal of High Energy Physics, 2020
We compute the superconformal index of 3d N $$ \mathcal{N} $$ = 2 superconformal field theories obtained from N M5-branes wrapped on a hyperbolic 3-manifold.

Strongly pseudo-convex CR space forms

Complex Manifolds, 2019
For a contact manifold, we study a strongly pseudo-convex CR space form with constant holomorphic sectional curvature for the Tanaka-Webster connection.

3d-3d correspondence for mapping tori

Journal of High Energy Physics, 2020
One of the main challenges in 3d-3d correspondence is that no existent approach offers a complete description of 3d N $$ \mathcal{N} $$ = 2 SCFT T [M 3] — or, rather, a “collection of SCFTs” as we refer to it in the paper — for all types of 3-manifolds ...

Homology of curves and surfaces in closed hyperbolic 3-manifolds [PDF]

, 2014
Among other things, we prove the following two topologcal statements about closed hyperbolic 3-manifolds. First, every rational second homology class of a closed hyperbolic 3-manifold has a positve integral multiple represented by an oriented connected ...

Universal circles for quasigeodesic flows [PDF]

, 2006
We show that if M is a hyperbolic 3-manifold which admits a quasigeodesic flow, then pi_1(M) acts faithfully on a universal circle by homeomorphisms, and preserves a pair of invariant laminations of this circle.

Fault-tolerant hyperbolic Floquet quantum error correcting codes [PDF]

Quantum
A central goal in quantum error correction is to reduce the overhead of fault-tolerant quantum computing by increasing noise thresholds and reducing the number of physical qubits required to sustain a logical qubit.

The virtual Haken conjecture: Experiments and examples [PDF]

, 2002
A 3-manifold is Haken if it contains a topologically essential surface. The Virtual Haken Conjecture says that every irreducible 3-manifold with infinite fundamental group has a finite cover which is Haken.

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

Hyperbolic Volumes of Two Bridge Cone-Manifolds

Известия Иркутского государственного университета: Серия "Математика"
In this paper we investigate the existence of hyperbolic, Euclidean and spherical structures on cone-manifolds with underlying space 3-sphere and with singular set a given two-bridge knot.
