Shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional manifold and their classification [PDF]

open access: yesریاضی و جامعه
This paper aims to study of shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional smooth manifold. In this study firstly we state formulae for the shape operator and its symmetric and anti-symmetric components and in ...

3d gravity as a random ensemble

open access: yesJournal of High Energy Physics
We give further evidence that the matrix-tensor model studied in [1] is dual to AdS3 gravity including the sum over topologies. This provides a 3D version of the duality between JT gravity and an ensemble of random Hamiltonians, in which the matrix and ...

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Isometric cusps in hyperbolic 3-manifolds.

open access: yesMichigan Mathematical Journal, 1999
Two cusps in a cusped finite volume hyperbolic \(3\)-manifold are called maximally isometric if their corresponding maximal cusps have isometric interiors. This paper provides a list of cusps, defined up to maximal isometry, such that given any cusp from the list and any cusped finite volume hyperbolic \(3\)-manifold \(M\), there exist two disjoint ...

Verified computations for closed hyperbolic 3‐manifolds [PDF]

open access: yesBulletin of the London Mathematical Society, 2020
Extending methods first used by Casson, we show how to verify a hyperbolic structure on a finite triangulation of a closed 3-manifold using interval arithmetic methods. A key ingredient is a new theoretical result (akin to a theorem by Neumann-Zagier and Moser for ideal triangulations upon which HIKMOT is based) showing that there is a redundancy among

Vol3 and other exceptional hyperbolic 3-manifolds [PDF]

open access: yesProceedings of the American Mathematical Society, 2000
``D. Gabai, R. Meyerhoff and N. Thurston identified seven families of exceptional hyperbolic manifolds in their proof that a manifold which is homotopy equivalent to a hyperbolic 3-manifold is hyperbolic. These families are each conjectured to consist of a single manifold. In fact, an important point in their argument depends on this conjecture holding

On commensurability of fibrations on a hyperbolic 3-manifold

open access: yes, 2013
We discuss fibered commensurability of fibrations on a hyperbolic 3-manifold, a notion introduced by Calegari, Sun and Wang. We construct manifolds with non-symmetric but commensurable fibrations on the same fibered face.

Nanophotonic Strategies for Chiral Biosensing: Nanoparticles, Metasurfaces, Magneto‐Optical, and Quantum Approaches

open access: yesAdvanced Photonics Research, EarlyView.
Recent advances in nanophotonics‐based chiral biosensing approaches are comprehensively reviewed, highlighting key trends, advantages, and limitations of each technology. Special attention is given to emerging strategies that exploit magneto‐optical and quantum plasmonic phenomena to enhance sensitivity down to the level of a few molecules, or even a ...

Shrinkwrapping and the taming of hyperbolic 3-manifolds [PDF]

open access: yes, 2004
We introduce a new technique for finding CAT(-1) surfaces in hyperbolic 3-manifolds. We use this to show that a complete hyperbolic 3-manifold with finitely generated fundamental group is geometrically and topologically tame.Comment: 60 pages, 7 figures;
