Noether symmetries and stability of ideal gas solutions in Galileon cosmology
(2017)
A class of generalized Galileon cosmological models, which can be described by a pointlike Lagrangian, is considered in order to utilize Noether's theorem to determine conservation laws for the field equations. In the ...
Behaviour of charged spinning massless particles
(Symmetry, 2019)
Scalar asymptotic charges and dual large gauge transformations
(Scuola Internazionale Superiore di Studi Avanzati (SISSA), 2019)
In recent years soft factorization theorems in scattering amplitudes have been reinterpreted as conservation laws of asymptotic charges. In gauge, gravity, and higher spin theories the asymptotic charges can be understood ...
Conservation laws for a coupled variable-coefficient modified Korteweg-de Vries system in a two-layer fluid model
(Elsevier Science BvAmsterdamHolanda, 2013)
Small oscillations: A new solution based on non-Noetherian symmetries
(1993)
A new (non-Noetherian) symmetry transformation for the small oscillations problem is exhibited. A novel way to solve this classical problem, based on conservation laws constructed using the new symmetry, is presented. ...
Conservation laws, hodograph transformation and boundary value problems of plane plasticity
(2012)
For the hyperbolic system of quasilinear first-order partial differential equations, linearizable by hodograph transformation, the conservation laws are used to solve the Cauchy problem. The equivalence of the initial ...

Moving frames for Lie symmetries reduction of nonholonomic systems
(2019-08-01)
Given a Lie group of finite-dimensional transformations acting on a manifold, there is always an action known as a long-acting group action. This action describes the fundamental basis of the Lie theory connecting groups ...
The modified Hunter-Saxton equation
(ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2012)
