Compactifications of indefinite 3-Sasaki structures and their quaternionic Kähler quotients

AR Gover, K Neusser, T Willse - Annali di Matematica Pura ed Applicata …, 2024 - Springer
We show that 3-Sasaki structures admit a natural description in terms of projective
differential geometry. First we establish that a 3-Sasaki structure may be understood as a …

Projective Geometry and PDE Prolongation

J McNaughton - arXiv preprint arXiv:2405.15175, 2024 - arxiv.org
In this dissertation we study basic local differential geometry, projective differential geometry,
and prolongations of overdetermined geometric partial differential equations. It is simple to …

Geometry of solutions to the c-projective metrizability equation

KJ Flood, AR Gover - Annali di Matematica Pura ed Applicata (1923-), 2023 - Springer
On an almost complex manifold, a quasi-Kähler metric, with canonical connection in the c-
projective class of a given minimal complex connection, is equivalent to a nondegenerate …

Projective geometry of 3-Sasaki structures

A Gover, K Neusser, T Willse - arXiv preprint arXiv:2204.08384, 2022 - arxiv.org
We show that $3 $-Sasaki structures admit a natural description in terms of projective
differential geometry. This description provides a concrete link between $3 $-Sasaki …

Conelike radiant structures

DJF Fox - Information Geometry, 2023 - Springer
Analogues of the classical affine-projective correspondence are developed in the context of
statistical manifolds compatible with a radiant vector field. These utilize a formulation of …

Dynamical Quantization of Contact Structures

R Casals, G Herczeg, A Waldron - arXiv preprint arXiv:2103.16645, 2021 - arxiv.org
We construct a dynamical quantization for contact manifolds in terms of a flat connection
acting on a Hilbert tractor bundle. We show that this contact quantization, which is …

Killing spinor-valued forms and their integrability conditions

P Somberg, P Zima - Annals of Global Analysis and Geometry, 2020 - Springer
We study invariant systems of PDEs defining Killing vector-valued forms, and then we
specialize to Killing spinor-valued forms. We give a detailed treatment of their prolongation …

[PDF][PDF] Asymptotically Hyperbolic Manifolds

Asymptotically hyperbolic (AH) manifolds continue to be an active area of modern research.
Much of the work is driven by the AdS/CFT correspondence. This really began with the …
