On the uniform perfectness of equivariant diffeomorphism groups for principal G manifolds [PDF]
Opuscula Mathematica, 2017 We proved in [K. Abe, K. Fukui, On commutators of equivariant diffeomorphisms, Proc. Japan Acad. 54 (1978), 52-54] that the identity component \(\text{Diff}\,^r_{G,c}(M)_0\) of the group of equivariant \(C^r\)-diffeomorphisms of a principal \(G\) bundle \

Martingales on principal fiber bundles
Proyecciones (Antofagasta), 2023 Let P(M,G) be a principal fiber bundle, let ω be a connection form on P(M,G), and consider a projectable connection ∇P on P(M,G). The aim of this work is to determine the ∇P -martingales in P(M,G). Our results allow establishing new characterizations of harmonic maps from Riemannian manifolds to principal fiber bundles.

The noncommutative geometry of Yang-Mills fields
, 2010 We generalize to topologically non-trivial gauge configurations the description of the Einstein-Yang-Mills system in terms of a noncommutative manifold, as was done previously by Chamseddine and Connes.

The Existence of Cartan Connections and Geometrizable Principal Bundles [PDF]
, 2004 The aim of this article is to proof a necessary and sufficient condition for the existence of a Cartan connection on a principal bundle. After collecting the essentially well known facts to fix the terminology, soldering forms and geometrizable principal

A construction of Shatz strata in the polystable $ G_2 $-bundles moduli space using Hecke curves
Electronic Research ArchiveLet $ X $ be a compact Riemann surface of genus $ g\geq 2 $ and $ M(G_2) $ be the moduli space of polystable principal $ G_2 $-bundles over $ X $. The Harder-Narasimhan types of the bundles induced a stratification of the moduli space $ M(G_2) $ called ...

Dunkl Operators as Covariant Derivatives in a Quantum Principal Bundle
Symmetry, Integrability and Geometry: Methods and Applications, 2013 A quantum principal bundle is constructed for every Coxeter group acting on a finite-dimensional Euclidean space E, and then a connection is also defined on this bundle.

Preoperative Cytopenia in Patients Affected by High‐Risk Neuroblastoma: Just a Matter of Platelets?
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background and Aims In patients affected by high‐risk neuroblastoma (HR‐NB), complete macroscopic resection (CMR) is associated with better outcomes. These patients are often cytopenic due to intensive induction regimens. The aim of the present study is to assess the impact of preoperative cytopenia on surgical outcome in patients with HR‐NB ...

Principal Bundles Over Finite Fields [PDF]
Communications in Algebra, 2011 Let M be an irreducible smooth projective variety defined over \bar{{\mathbb F}_p}. Let (M, x_0) be the fundamental group scheme of M with respect to a base point x_0. Let G be a connected semisimple linear algebraic group over \bar{{\mathbb F}_p}. Fix a parabolic subgroup P \subsetneq G, and also fix a strictly anti-dominant character of P.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

Developmental Disorders in Children Recently Diagnosed With Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Neurocognitive deficits in adult survivors of childhood cancer are well established, but less is known about developmental disorders (DD) arising shortly after cancer diagnosis. Using 2016–2019 linked Ohio cancer registry and Medicaid data, we compared DD among 324 children with cancer and 606,913 cancer‐free controls.
