Nontrivial bundles and defect operators in n-form gauge theories

Journal of High Energy Physics
In (d + 1)-dimensional 1-form nonabelian gauge theories, we classify nontrivial 0-form bundles in ℝ d , which yield configurations of D(d − 2j)-branes wrapping (d − 2j)-cycles c d−2j in Dd-branes. We construct the related defect operators U (2j−1)(c d−2j

Chern-Simons forms for R-linear connections on Lie algebroids

, 2011
The Chern-Simons forms for R-linear connections on Lie algebroids are considered. A generalized Chern-Simons formula for such R-linear connections is obtained. We it apply to define Chern character and secondary characteristic classes for R-linear connections of Lie algebroids.

On Chern-Simons Matrix Models

, 2006
The contribution of reducible connections to the U(N) Chern-Simons invariant of a Seifert manifold $M$ can be expressed in some cases in terms of matrix integrals.

Chern classes for coherent sheaves [PDF]

We present in this paper a construction of Chern classes for a coherent sheaf S on a complex manifold X. In fact we construct classes Cp(S) in H2p(X, C), depending only on the smooth equivalence class of the sheaf S. and analytic classes CAp(S) in Hp(
