Singular reduction for proper actions [PDF]

open access: yes, 2000
The goal of this paper is to give a simplied proof of the singular reduction theorem for a proper Hamiltonian action of a Lie group G on a connected smooth symplectic manifold P which has a coadjoint equivariant mo mentum mapping Our proof does not use the assumption that the coadjoint orbit is locally closed any local normal form or the shifting trick

Remarks on Existence of Proper Action for Reducible Gauge Theories [PDF]

open access: yes, 2009
In the field-antifield formalism, we review existence and uniqueness proofs for the proper action in the reducible case. We give two new existence proofs based on two resolution degrees called "reduced antifield number" and "shifted antifield number ...

Population-level investigation of the knowledge of ocular chemical injuries and proper immediate action

open access: yesBMC Research Notes, 2020
Objective Although the eyes occupy 0.1% of the total body surface, eye injuries are serious because vision is arguably the most important sense. We aimed to assess knowledge of Saudi Arabian residents regarding steps to be taken in cases of chemical eye ...

South Asian Working Action Group on SARCOpenia (SWAG-SARCO) – A consensus document

open access: yesOsteoporosis and Sarcopenia, 2022
The South Asian population is rapidly ageing and sarcopenia is likely to become a huge burden in this region if proper action is not taken in time. Several sarcopenia guidelines are available, from the western world and from East Asia.

A Decision-Making Method for Autonomous Collision Avoidance for the Stand-On Vessel Based on Motion Process and COLREGs

open access: yesJournal of Marine Science and Engineering, 2021
A great number of collision accidents can be attributed to incongruous collision-avoidance actions between the give-way vessel and the stand-on vessel in a crossing or overtaking situation.

Affine Anosov Representations and Proper Actions

open access: yesInternational Mathematics Research Notices, 2022
Abstract We define the notion of affine Anosov representations of word hyperbolic groups into the affine group $\textsf {SO}^0(n+1,n)\ltimes {\mathbb {R}}^{2n+1}$. We then show that a representation $\rho $ of a word hyperbolic group is affine Anosov if and only if its linear part $\mathtt {L}_\rho $ is Anosov in $\textsf {SO}^0(n+1,n ...

Slice Theorem For Differential Spaces And Reduction By Stages

open access: yesDemonstratio Mathematica, 2014
We show that the space P/G of orbits of a proper action of a Lie group G on a locally compact differential space P is a locally compact differential space with quotient topology.

Proper motions and dynamics of the Milky Way globular cluster system fromGaiaDR2 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We use Gaia Data Release 2 to determine the mean proper motions for 150 Milky Way globular clusters (almost the entire known population), with a typical uncertainty of 0.05 mas/yr limited mainly by systematic errors. Combining them with distance and line-

Unfolded dynamics approach and quantum field theory

open access: yesJournal of High Energy Physics, 2023
We study quantization of a self-interacting scalar field within the unfolded dynamics approach. To this end we find and analyze a classical unfolded system describing 4d off-shell scalar field with a general self-interaction potential.
