Airy structures and symplectic geometry of topological recursion [PDF]

open access: yesProceedings of Symposia in Pure Mathematics, 2017
We propose a new approach to the topological recursion of Eynard-Orantin based on the notion of Airy structure, which we introduce in the paper. We explain why Airy structure is a more fundamental object than the one of the spectral curve. We explain how

Symplectic Entropy as a Novel Measure for Complex Systems

open access: yesEntropy, 2016
Real systems are often complex, nonlinear, and noisy in various fields, including mathematics, natural science, and social science. We present the symplectic entropy (SymEn) measure as well as an analysis method based on SymEn to estimate the ...

Virasoro entanglement Berry phases

open access: yesJournal of High Energy Physics, 2022
We study the parallel transport of modular Hamiltonians encoding entanglement properties of a state. In the case of 2d CFT, we consider a change of state through action with a suitable diffeomorphism on the circle: one that diagonalizes the adjoint ...

An invitation to singular symplectic geometry [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics (IJGMMP), 2017
In this paper, we analyze in detail a collection of motivating examples to consider [Formula: see text]-symplectic forms and folded-type symplectic structures.

Symplectic Geometry and Spectral Properties of Classical and Quantum Coupled Angular Momenta [PDF]

open access: yesJournal of nonlinear science, 2016
We give a detailed study of the symplectic geometry of a family of integrable systems obtained by coupling two angular momenta in a non-trivial way. These systems depend on a parameter t∈[0,1]\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{

Lie Group Cohomology and (Multi)Symplectic Integrators: New Geometric Tools for Lie Group Machine Learning Based on Souriau Geometric Statistical Mechanics

open access: yesEntropy, 2020
In this paper, we describe and exploit a geometric framework for Gibbs probability densities and the associated concepts in statistical mechanics, which unifies several earlier works on the subject, including Souriau’s symplectic model of statistical ...

Conformal symplectic geometry of cotangent bundles [PDF]

open access: yesThe Journal of Symplectic Geometry, 2016
We prove a version of the Arnol'd conjecture for Lagrangian submanifolds of conformal symplectic manifolds: a Lagrangian $L$ which has non-zero Morse-Novikov homology for the restriction of the Lee form $\beta$ cannot be disjoined from itself by a $C^0 ...

Generalised Complex Geometry in Thermodynamical Fluctuation Theory

open access: yesEntropy, 2015
We present a brief overview of some key concepts in the theory of generalized complex manifolds. This new geometry interpolates, so to speak, between symplectic geometry and complex geometry.

Feature Extraction of Gearbox Early Fault based on ISGMD and MED

open access: yesJixie chuandong, 2022
Aiming at the difficulty in identifying early faults and compound faults of gearboxes under strong noise background,a method of extracting fault features based on the combination of improved symplectic geometry mode decomposition (ISGMD) and minimum ...
