Quasi-metric connections and a conjecture of Chern on affine manifolds

, 2015
In this paper we define the Euler form for a general linear connection which satisfies some minor compatibility condition to a given metric. Using this construction we prove that every closed,affine manifold has zero Euler characteristic.

Characterization of Isoclinic, Transversally Geodesic and Grassmannizable Webs

Axioms
One of the most relevant topics in web theory is linearization. A particular class of linearizable webs is the Grassmannizable web. Akivis gave a characterization of such a web, showing that Grassmannizable webs are equivalent to isoclinic and ...

On the induced connection on sections of Toeplitz operators

Modern Mathematical Methods
The purpose of the present article is to show that an upper bound of the induced connection on sections of Toeplitz operators is bounded by a function of the Hankel and of the Toeplitz operators on a weighted Hilbert Bergman space on a bounded domain of ...

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
