Principal non-commutative torus bundles [PDF]

open access: yesProceedings of the London Mathematical Society, 2008
In this paper we study continuous bundles of C*-algebras which are non-commutative analogues of principal torus bundles. We show that all such bundles, although in general being very far away from being locally trivial bundles, are at least locally trivial with respect to a suitable bundle version of bivariant K-theory (denoted RKK-theory) due to ...

Stable Higgs bundles over positive principal elliptic fibrations

open access: yesComplex Manifolds, 2018
Let M be a compact complex manifold of dimension at least three and Π : M → X a positive principal elliptic fibration, where X is a compact Kähler orbifold. Fix a preferred Hermitian metric on M.

Deformation quantization of principal bundles [PDF]

open access: green, 2016
We outline how Drinfeld twist deformation techniques can be applied to the deformation quantization of principal bundles into noncommutative principal bundles, and more in general to the deformation of Hopf-Galois extensions.

Monodromy group for a strongly semistable principal bundle over a curve, II [PDF]

open access: bronze, 2008
Let $X$ be a geometrically irreducible smooth projective curve defined over a field $k$. Assume that $X$ has a $k$-rational point; fix a $k$-rational point $x\in X$.

Characteristic principal bundles [PDF]

open access: yesTransactions of the American Mathematical Society, 1975
Characteristic principal bundles are the duals of commutative twisted group algebras. A principal bundle with locally compact second countable (Abelian) group and base space is characteristic iff it supports a continuous eigenfunction for almost every character measurably in the characters, also iff it is the quotient by Z of a principal E-bundle for ...

n-Tuple principal bundles [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2018
We develop the concept of a double (more generally [Formula: see text]-tuple) principal bundle departing from a compatibility condition for a principal action of a Lie group on a groupoid.

Chern character in twisted K-theory: equivariant and holomorphic cases [PDF]

open access: yes, 2002
It has been argued by Witten and others that in the presence of a nontrivial B-field, D-brane charges in type IIB string theories are measured by twisted K-theory.
