[图书][B] Generalized Ricci Flow

M Garcia-Fernandez, J Streets - 2021 - books.google.com
The generalized Ricci flow is a geometric evolution equation which has recently emerged
from investigations into mathematical physics, Hitchin's generalized geometry program, and …

The geometry of E-manifolds

E Miranda, G Scott - Rev. Mat. Iberoam, 2021 - ems.press
Motivated by the study of symplectic Lie algebroids, we focus on a type of algebroid (called
an E-tangent bundle) which is particularly well-suited to the study of singular differential …

Poisson geometry around Poisson submanifolds

RL Fernandes, I Mărcuţ - Journal of the European Mathematical Society, 2024 - ems.press
We construct a first-order local model for Poisson manifolds around a large class of Poisson
submanifolds and give conditions under which this model is a local normal form. The …

Regularisation of Lie algebroids and applications

Á del Pino, A Witte - Journal of Geometry and Physics, 2023 - Elsevier
We describe a procedure, called regularisation, that allows us to study geometric structures
on Lie algebroids via foliated geometric structures on manifolds of higher dimension. This …

Hamiltonian facets of classical gauge theories on E-manifolds

P Mir, E Miranda, P Nicolás - Journal of Physics A: Mathematical …, 2023 - iopscience.iop.org
Manifolds with boundary, with corners, b-manifolds and foliations model configuration
spaces for particles moving under constraints and can be described as E-manifolds. E …

Non-principal T-duality, generalized complex geometry and blow-ups

GR Cavalcanti, A Witte - arXiv preprint arXiv:2211.17173, 2022 - arxiv.org
We extend the notion of T-duality to manifolds endowed with non-principal torus actions. The
singularities of the torus action are controlled by a certain Lie algebroid, called the elliptic …

Jets of foliations and -algebroids

F Bischoff, Á del Pino, A Witte - arXiv preprint arXiv:2311.17045, 2023 - arxiv.org
In this article, we introduce and study singular foliations of $ b^ k $-type. These singular
foliations formalize the properties of vector fields that are tangent to order $ k $ along a …

Self-crossing stable generalized complex structures

GR Cavalcanti, RL Klaasse, A Witte - arXiv preprint arXiv:2004.07559, 2020 - arxiv.org
We extend the notion of (smooth) stable generalized complex structures to allow for an
anticanonical section with normal self-crossing singularities. This weakening not only allows …

Geometric structures and Lie algebroids

RL Klaasse - arXiv preprint arXiv:1712.09560, 2017 - arxiv.org
In this thesis we study geometric structures from Poisson and generalized complex geometry
with mild singular behavior using Lie algebroids. The process of lifting such structures to …

Linearization of Poisson groupoids

W Smilde - Indagationes Mathematicae, 2022 - Elsevier
Motivated by a search for Lie group structures on groups of Poisson diffeomorphisms, we
investigate linearizability of Poisson structures of Poisson groupoids around the unit section …
