Palatini Gauss-Bonnet theory

open access: yesJournal of High Energy Physics
We consider a class of models in even spacetime dimensions 2n which share many similarities with Chern-Simons theories in odd spacetime dimensions 2n + 1.

Characterization of Isoclinic, Transversally Geodesic and Grassmannizable Webs

open access: yesAxioms
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 ...

The Levi-Civita connection and Chern connections for cocycle deformations of Kähler manifolds

open access: yes
We consider unitary cocycle deformations of covariant $\ast$-differential calculi. We prove that complex structures, holomorphic bimodules and Chern connections on the deformed calculus are twists of their untwisted counterparts. Moreover, for cocycle deformations of a class of classical Kähler manifolds, the Levi-Civita connection on the space of one ...

Jacobi Stability Analysis of Liu System: Detecting Chaos

open access: yesMathematics
By utilizing the Kosambi–Cartan–Chern (KCC) geometric theory, this paper is dedicated to providing novel insights into the Liu dynamical system, which stands out as one of the most distinctive and noteworthy nonlinear dynamical systems.

Nontrivial bundles and defect operators in n-form gauge theories

open access: yesJournal 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

open access: yes, 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.

An elliptic integrable deformation of the Principal Chiral Model

open access: yesJournal of High Energy Physics
We introduce a new elliptic integrable σ-model in the form of a two-parameter deformation of the Principal Chiral Model on the group SLℝ(N), generalising a construction of Cherednik for N = 2 (up to reality conditions).
