Inverse problems for nonlinear hyperbolic equations with disjoint sources and receivers

open access: yesForum of Mathematics, Pi, 2021
The article studies inverse problems of determining unknown coefficients in various semi-linear and quasi-linear wave equations given the knowledge of an associated source-to-solution map.

Multiple Closed Geodesics on Positively Curved Finsler Manifolds

open access: yesAdvanced 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

open access: yesJournal 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

open access: yesComplex 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.

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

open access: yes, 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 ...

3d-3d correspondence for mapping tori

open access: yesJournal 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 ...

CUSP DENSITIES OF HYPERBOLIC 3-MANIFOLDS [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 2002
AbstractThe cusp density of a hyperbolic 3-manifold is the ratio of the largest possible volume in a set of cusps with disjoint interiors to the volume in the manifold. It is known that all cusp densities fall in the interval $[0,0.853\dots]$. It is shown that the cusp densities of finite-volume orientable hyperbolic 3-manifolds are dense in this ...

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

open access: yesQuantum
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.
