A generalized 4d Chern-Simons theory [PDF]

open access: yesJournal of High Energy Physics, 2023
A generalization of the 4d Chern-Simons theory action introduced by Costello and Yamazaki is presented. We apply general arguments from symplectic geometry concerning the Hamiltonian action of a symmetry group on the space of gauge connections defined on

A note on η-quasi-umbilical hypersurfaces in almost Hermitian manifolds

open access: yesДифференциальная геометрия многообразий фигур, 2023
In the present note, we consider the introduced by Lidia Vasil’evna Stepanova notion of an -quasi-umbilical hypersurface in an almost Her­mitian manifold.

Invariants and Infinitesimal Transformations for Contact Sub-Lorentzian Structures on 3-Dimensional Manifolds [PDF]

open access: yes, 2014
In this article we develop some elementary aspects of a theory of symmetry in sub-Lorentzian geometry. First of all we construct invariants characterizing isometric classes of sub-Lorentzian contact 3 manifolds.

Supersymmetric Field Theories on Three-Manifolds [PDF]

open access: yes, 2013
We construct supersymmetric field theories on Riemannian three-manifolds M, focusing on N=2 theories with a U(1)_R symmetry. Our approach is based on the rigid limit of new minimal supergravity in three dimensions, which couples to the flat-space ...

Issues in Topological Gauge Theory [PDF]

open access: yes, 1998
We discuss topological theories, arising from the general $\mathcal{N}=2$ twisted gauge theories. We initiate a program of their study in the Gromov-Witten paradigm.

Gravitational descendants in symplectic field theory

open access: yes, 2010
It was pointed out by Y. Eliashberg in his ICM 2006 plenary talk that the rich algebraic formalism of symplectic field theory leads to a natural appearance of quantum and classical integrable systems, at least in the case when the contact manifold is the

Comments on contact terms and conformal manifolds in the AdS/CFT correspondence [PDF]

open access: yesProgress of Theoretical and Experimental Physics, 2020
We study the contact terms that appear in the correlation functions of exactly marginal operators using the anti-de Sitter/conformal field theory (AdS/CFT) correspondence. It is known that CFT with an exactly marginal deformation requires the existence

Extended Hamilton–Jacobi theory, contact manifolds, and integrability by quadratures [PDF]

open access: yesJournal of Mathematics and Physics, 2019
A Hamilton-Jacobi theory for general dynamical systems, defined on fibered phase spaces, has been recently developed. In this paper we shall apply such a theory to contact Hamiltonian systems, as those appearing in thermodynamics and on geodesic flows in

Cylindrical contact homology of 3–dimensional Brieskorn manifolds [PDF]

open access: yesAlgebraic & Geometric Topology, 2019
Cylindrical contact homology is a comparatively simple incarnation of symplectic field theory whose existence and invariance under suitable hypotheses was recently established by Hutchings and Nelson.

Special lines on contact manifolds [PDF]

open access: yesAnnales de l'Institut Fourier, 2014
In a series of two articles Kebekus studied deformation theory of minimal rational curves on contact Fano manifolds. Such curves are called contact lines.
