Generalized Laplace Particle Filter on Lie Groups Applied to Ambiguous Doppler Navigation
Autor: Clement Chahbazian, Nicolas Merlinge, Karim Dahia, Benedicte Winter-Bonnet, Aurelien Blanc, Christian Musso
Publikováno v: 2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS).
Particle filters are suited to solve nonlinear and non-Gaussian estimation problems which find numerous applications in autonomous systems navigation. Previous works on Laplace Particle Filter on Lie groups (LG-LPF) demonstrated its robustness and ac

Filtrage Particulaire sur Groupes de Lie
Autor: Chahbazian, Clément, Dahia, Karim, Merlinge, Nicolas, Winter-Bonnet, Bénédicte, Blanc, Aurélien, Musso, Christian
Les filtres particulaires sont une famille de méthodes numériques permettant de traiter des problèmes d'estimation non-linéaires et non-Gaussiens. Ils constituent un domaine de recherche actif. En particulier, les nouveaux travaux sur le filtre p

Cohomologie des formes différentielles co-invariantes et sous-groupes abéliens sans torsion de groupes de Lie
Autor: Mehdi Nabil

The first part of this thesis focuses on the theme of group actions on smooth manifolds and cohomology. Our contribution was to introduce a new differential subcomplex of the de Rham complex that can be attached to group actions on smooth manifolds,

Noncubic Dirac Operators for finite-dimensional modules
Autor: Afentoulidis Almpanis, Spyridon
Publikováno v: Mathematics [math]. Université de Lorraine, 2021. English. ⟨NNT : 2021LORR0035⟩
This thesis focuses on the study of noncubic Dirac operators within the framework of representation theory of Lie groups. After recalling basic notions of Lie theory and Clifford algebras, we present the main properties of cubic Dirac operators D int

Géométrie des variétés de représentations dans des groupes de Lie résolubles et géométrie en dimension 3
Autor: Berat, Clément
In this thesis, we are interested in the character variety of a surface group with respect to a solvable Lie group.This is the the set of all homomorphisms of the fundamental group of a surface taking values in a Lie group, up to conjugacy.Character

Asymptotic representation theory and applications to Yang-Mills theory
Autor: Lemoine, Thibaut
Publikováno v: Physique mathématique [math-ph]. Sorbonne Universite, 2020. Français
This thesis is devoted to the study of Yang–Mills measure on a compact surface, with structure group the unitary group U(N) or special unitary group SU(N). This study is more precisely about this measure’s asymptotic behaviour in the large N limi

Explicit bounds for graph minors
Autor: R. Bruce Richter, Jim Geelen, Tony Huynh
Publikováno v: Journal of combinatorial theory. Series B
Let Σ be a surface with boundary bd(Σ), L be a collection of k disjoint bd(Σ)-paths in Σ, and P be a non-separating bd(Σ)-path in Σ. We prove that there is a homeomorphism ϕ:Σ→Σ that fixes each point of bd(Σ) and such that ϕ(L) meets P a

We consider the KdV equation on a circle and its Lie-Poisson reconstruction, which is reminiscent of an equation of motion for fluid particles. For periodic waves, the stroboscopic reconstructed motion is governed by an iterated map whose Poincar\'e
