Conservation laws and normal forms of evolution equations
, 2010 We study local conservation laws for evolution equations in two independent variables. In particular, we present normal forms for the equations admitting one or two low-order conservation laws.

A geometric study of the dispersionless Boussinesq type equation [PDF]
, 2005 We discuss the dispersionless Boussinesq type equation, which is equivalent to the Benney-Lax equation, being a system of equations of hydrodynamical type. This equation was discussed in .

Loop scattering in two-dimensional QCD [PDF]
, 1995 Using the integrability conditions that we recently obtained in QCD$_2$ with massless fermions, we arrive at a sufficient number of conservation laws to be able to fix the scattering amplitudes involving a local version of the Wilson loop operator ...

Extension the Noether's theorem to Lagrangian formulation with nonlocality
, 2012 A Lagrangian formulation with nonlocality is investigated in this paper. The nonlocality of the Lagrangian is introduced by a new nonlocal argument that is defined as a nonlocal residual satisfying the zero mean condition.

New Integrable Nonlinear Lattice Systems with Two Adjustable Coupling Parameters
Nonlinear Engineering, 2013 The double reduction when having been applied to the fourth-order spectral operator on a discrete spatial support is shown to inspire early unknown multicomponent semidiscrete integrable nonlinear systems associated with the nonsinglular spectral

Microscopic local conservation laws for classical fluids [PDF]
The European Physical Journal Special Topics, 2015 The local densities and current densities of conserved quantities are expressed in a tutorial scope, for a fluid under arbitrary off-equilibrium conditions, in terms of the two-particle potential W(r) and of the one- and two-particle densities in phase space f and f2.

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Numerical Study of a Thermally Stressed State of a Rod
Advances in Mathematical Physics, 2019 This paper considers a new method based on the law of energy conservation for the study of thermo-stress-strain state of a rod of limited length with simultaneous presence of local heat fluxes, heat exchanges, and thermal insulation.

Symmetries and Local Conservation Laws of Variational Schemes for the Surface Plasmon Polaritons
, 2019 The relation between symmetries and local conservation laws, known as Noether's theorem, plays an important role in modern theoretical physics. As a discrete analog of the differentiable physical system, a good numerical scheme should admit the discrete ...
