چکیده
This paper analyses the Noether symmetries and the corresponding conservation laws for Chern-Simons Lagrangians in dimension d = 3. In particular, we find an expression for the superpotential of ChernSimons gravity. As a by-product the general discussion of superpotentials for 3rd order natural and quasi-natural theories is also given. PACS number(s): 04.20.Fy, 11.10Kk, 11.30.-j, 04.20.Cv

Axion gauge symmetries and generalized Chern – Simons terms in N = 1 supersymmetric theories
We compute the extension of the Lagrangian of N = 1 supersymmetric theories to the case in which some axion symmetries are gauged. It turns out that generalized Chern–Simons terms appear that were not considered in previous superspace formulations of general N = 1 theories. Such gaugings appear in supergravities arising from flux compactifications of superstrings, as well as from Scherk–Schwarz...
متن کاملOn Symmetries of Chern-Simons and BF Topological Theories
We describe constructing solutions of the field equations of Chern-Simons and topological BF theories in terms of deformation theory of locally constant (flat) bundles. Maps of flat connections into one another (dressing transformations) are considered. A method of calculating (nonlocal) dressing symmetries in Chern-Simons and topological BF theories is formulated.
متن کاملConnection vs metric description for non-AdS solutions in higher spin theories
We consider recently-constructed solutions of three dimensional SL(N,R)×SL(N,R) Chern-Simons theories with non-relativistic symmetries. Solutions of the Chern-Simons theories can generically be mapped to solutions of a gravitational theory with a higherspin gauge symmetry. However, we will show that some of the non-relativistic solutions are not equivalent to metric solutions, as this mapping f...
متن کاملDynamics of N=2 Supersymmetric Chern-Simons Theories
We discuss several aspects of three dimensional N = 2 supersymmetric gauge theories coupled to chiral multiplets. The generation of Chern-Simons couplings at lowenergies results in novel behaviour including compact Coulomb branches, non-abelian gauge symmetry enhancement and interesting patterns of dynamically generated potentials. We further show how, given any pair of mirror theories with N =...
متن کاملGeneralised Chern-Simons actions for 3d gravity and κ-Poincaré symmetry
We consider Chern-Simons theories for the Poincaré, de Sitter and anti-de Sitter groups in three dimensions which generalise the Chern-Simons formulation of 3d gravity. We determine conditions under which κ-Poincaré symmetry and its de Sitter and anti-de Sitter analogues can be associated to these theories as quantised symmetries. Assuming the usual form of those symmetries, with a timelike vec...
