Hessian metric via transport information geometry [PDF]

open access: yesJournal of Mathematics and Physics, 2020
We propose to study the Hessian metric of given functional in the space of probability space embedded with $L^2$--Wasserstein (optimal transport) metric.

A Point-to-Distribution Joint Geometry and Color Metric for Point Cloud Quality Assessment [PDF]

open access: yesIEEE International Workshop on Multimedia Signal Processing, 2021
Point clouds (PCs) are a powerful 3D visual representation paradigm for many emerging application domains, especially virtual and augmented reality, and autonomous vehicles. However, the large amount of PC data required for highly immersive and realistic

Joint Geometry and Color Projection-Based Point Cloud Quality Metric [PDF]

open access: yesIEEE Access, 2021
Point cloud coding solutions have been recently standardized to address the needs of multiple application scenarios. The design and assessment of point cloud coding methods require reliable objective quality metrics to evaluate the level of degradation ...

On the Geometry of Tangent Bundle and Unit Tangent Bundle with Deformed-Sasaki Metric

open access: yesInternational Electronic Journal of Geometry, 2023
Let $(M^{m}, g)$ be a Riemannian manifold and $TM$ its tangent bundle equipped with a deformed Sasaki metric. In this paper, firstly we investigate all forms of Riemannian curvature tensors of $TM$ (Riemannian curvature tensor, Ricci curvature, sectional

PFH spectral invariants on the two-sphere and the large scale geometry of Hofer’s metric [PDF]

open access: yesJournal of the European Mathematical Society (Print), 2021
We resolve three longstanding questions related to the large scale geometry of the group of Hamiltonian diffeomorphisms of the two-sphere, equipped with Hofer's metric.

Relating the topology of Dirac Hamiltonians to quantum geometry: When the quantum metric dictates Chern numbers and winding numbers [PDF]

open access: yesSciPost Physics, 2021
Quantum geometry has emerged as a central and ubiquitous concept in quantum sciences, with direct consequences on quantum metrology and many-body quantum physics. In this context, two fundamental geometric quantities are known to play complementary roles:

New characterizations of reproducing kernel Hilbert spaces and applications to metric geometry [PDF]

open access: yesOpuscula Mathematica, 2020
We give two new global and algorithmic constructions of the reproducing kernel Hilbert space associated to a positive definite kernel. We further present a general positive definite kernel setting using bilinear forms, and we provide new examples.

m-quasi Einstein Metric and Paracontact Geometry

open access: yesInternational Electronic Journal of Geometry, 2022
The object of the upcoming article is to characterize paracontact metric manifolds conceding $m$-quasi Einstein metric. First we establish that if the metric $g$ in a $K$-paracontact manifold is the $m$-quasi Einstein metric, then the manifold is of ...
