Fivebranes and 3-manifold homology
Journal of High Energy Physics, 2017 Motivated by physical constructions of homological knot invariants, we study their analogs for closed 3-manifolds. We show that fivebrane compactifications provide a universal description of various old and new homological invariants of 3-manifolds.

Symmetric Space Cartan Connections and Gravity in Three and Four Dimensions
Symmetry, Integrability and Geometry: Methods and Applications, 2009 Einstein gravity in both 3 and 4 dimensions, as well as some interesting generalizations, can be written as gauge theories in which the connection is a Cartan connection for geometry modeled on a symmetric space.

The FASEB Journal, Volume 40, Issue 18, 30 September 2026.Ellagic acid potentiates RSL3‐induced ferroptosis in PANC‐1 by suppressing the Nrf2/HO‐1 antioxidant defense axis via p38 MAPK activation and Keap1 upregulation. In PDAC cells, constitutive Nrf2/HO‐1 signaling establishes a robust antioxidant shield (GPX4, HO‐1) that limits lipid ROS accumulation and confers ferroptosis resistance.

Strong connections and the relative Chern-Galois character for corings
, 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.

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.Nonlinear photocurrents provide broadband spectroscopic access to quantum materials from terahertz to optical frequencies. Their sensitivity to spin, orbital, chiral, topological, and quantum‐geometric properties enables insights across ferroelectrics, magnetic and two‐dimensional materials, moiré heterostructures, topological flat bands, and light ...

Abelian Chern–Simons theory, Stokes’ theorem, and generalized connections
Journal of Geometry and Physics, 2012 Generalized connections and their calculus have been developed in the context of quantum gravity. Here we apply them to abelian Chern-Simons theory. We derive the expectation values of holonomies in U(1) Chern-Simons theory using Stokes' theorem, flux operators and generalized connections. A framing of the holonomy loops arises in our construction, and

Explicit construction of a Chern–Moser connection for CR manifolds of codimension two [PDF]
Annali di Matematica Pura ed Applicata, 2005 In the present paper we suggest an explicit construction of a Cartan connection for an elliptic or hyperbolic CR manifold M of dimension six and codimension two, i.e. a pair (P, w), consisting of a principal bundle P over M and of a Cartan connection form w on P, satisfying the following property: the (local) CR transformations of M are in one to one ...

Higher dimensional quantum Hall effect as A-class topological insulator
Nuclear Physics B, 2014 We perform a detail study of higher dimensional quantum Hall effects and A-class topological insulators with emphasis on their relations to non-commutative geometry.
