On Hermitian manifolds whose Chern connection is Ambrose-Singer

open access: greenTransactions of the American Mathematical Society, 2022
We consider the class of compact Hermitian manifolds whose Chern connection is Ambrose-Singer, namely, it has parallel torsion and curvature. We prove structure theorems for such manifolds.

Chern currents of singular connections associated with a section of a compactified bundle [PDF]

open access: bronzeIndiana University Mathematics Journal, 1995
A compactification of the Chern-Weil theory for bundle maps, developed by \textit{F. R. Harvey} and \textit{H. B. Lawson jun.} [Astérisque 213, 268 (1993; Zbl 0804.53037)], is described. For each section \(\nu\) of the compactification \(\mathbb{P} (\underline \mathbb{C} \oplus F) \to X\) of a rank \(n\) complex vector bundle \(F \to X\) with ...

Strong connections and the relative Chern-Galois character for corings

open access: greenInternational Mathematics Research Notices, 2005
The Chern-Galois theory is developed for corings or coalgebras over non-commutative rings. As the first step the notion of an entwined extension as an extension of algebras within a bijective entwining structure over a non-commutative ring is introduced.

Spectral triples from bimodule connections and Chern connections [PDF]

open access: greenJournal of Noncommutative Geometry, 2017
We give a geometrical construction of Connes spectral triples or noncommutative Dirac operators \def\Dslash{{\mathrlap{\,/}{D}}}\Dslash starting with a bimodule connection on the proposed spinor bundle. The theory is applied to the example of M_2(\mathbb C)

A symmetric Finsler space with Chern connection

open access: green, 2007
We define a symmetry for a Finsler space with Chern connection and investigate its implementation and properties and find a relation between them and flag curvature.

Chern connections and Chern curvature of the tangent bundle of almost complex manifolds

open access: green, 2004
The $\bar{\partial}_{_{J}}$ operator over an almost complex manifold induces canonical connections of type $(0,1)$ over the bundles of $(p,0)$-forms. If the almost complex structure is integrable then the previous connections induce the canonical holomorphic structures of the bundles of $(p,0)$-forms.

Super Chern–Simons theory and flat super connections on a torus [PDF]

open access: bronzeAdvances in Theoretical and Mathematical Physics, 2001
We study the moduli space of a super Chern-Simons theory on a manifold with the topology ${\bf R}\times $, where $ $ is a compact surface. The moduli space is that of flat super connections modulo gauge transformations on $ $, and we study in detail the case when $ $ is atorus and the supergroup is $OSp(m|2n)$.
