(2,0) lagrangian structures

Physics Letters B, 2019
By including an additional self-dual three-form we construct a Lorentz invariant lagrangian for the abelian (2,0) tensor supermultiplet. The extra three-form is a supersymmetry singlet and decouples from the (2,0) tensor supermultiplet.

Formal Lagrangian Operad [PDF]

International Journal of Mathematics and Mathematical Sciences, 2010
Given a symplectic manifold M, we may define an operad structure on the the spaces Ok of the Lagrangian submanifolds of (M¯)k×M via symplectic reduction.

Stochastic reconstruction of gappy Lagrangian turbulent signals by conditional diffusion models

Communications Physics
Understanding and predicting the motion of small objects in turbulent flows is essential for applications in atmospheric science and oceanography. However, missing velocity data along their trajectories remains a major challenge.

Routh Reduction by Stages

Symmetry, Integrability and Geometry: Methods and Applications, 2011
This paper deals with the Lagrangian analogue of symplectic or point reduction by stages. We develop Routh reduction as a reduction technique that preserves the Lagrangian nature of the dynamics.

Higgs Effective Lagrangian

EPJ Web of Conferences, 2013
We present a short overview of the main aspects of the Higgs Effective Lagrangian. In particular we highlight a strategy to determine whether the electroweak symmetry breaking sector is controlled by a strong or a weak dynamics.

Generalized Poincaré algebras and Lovelock–Cartan gravity theory

Physics Letters B, 2015
We show that the Lagrangian for Lovelock–Cartan gravity theory can be reformulated as an action which leads to General Relativity in a certain limit. In odd dimensions the Lagrangian leads to a Chern–Simons theory invariant under the generalized Poincaré

Classical Higgs fields on gauge gluon bundles

EPJ Web of Conferences, 2016
Classical Higgs fields and related canonical conserved quantities are defined by invariant variational problems on suitably defined gauge gluon bundles. We consider Lagrangian field theories which are assumed to be invariant with respect to the action of

Lagrangian Modelling and Motion Stability of Synchronous Generator-based Power Systems

CSEE Journal of Power and Energy Systems
This paper proposes to analyze the motion stability of synchronous generator-based power systems using a Lagrangian model derived in the configuration space of generalized position and speed.

Can Eulerian Eddy Diffusivity Be Inferred From Lagrangian Trajectories?

Journal of Advances in Modeling Earth Systems
Lagrangian particle trajectories are widely used to characterize tracer dispersion and mixing driven by mesoscale currents (“eddies”), leading to estimates of eddy diffusivity that can in turn be used in non‐eddy‐resolving and eddy‐permitting ocean ...
