“Irregularization” of systems of conservation laws

open access: yesMaterials Theory, 2018
We explore new ways of regulating defect behavior in systems of conservation laws. Contrary to usual regularization schemes (such as a vanishing viscosity limit), which attempt to control defects by making them smoother, our schemes result in defects ...

New electromagnetic conservation laws [PDF]

open access: yes, 2003
The Chevreton superenergy tensor was introduced in 1964 as a counterpart, for electromagnetic fields, of the well-known Bel-Robinson tensor of the gravitational field.

Conservation laws for incompressible fluids

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
By means of a direct approach, a complete set of conservation laws for incompressible fluids is determined. The problem is solved in the material (Lagrangian) description and the results are eventually rewritten in the spatial (Eulerian) formulation.

SYMMETRY AND CONSERVATION LAWS [PDF]

open access: yesProceedings of the National Academy of Sciences, 1964
Symmetry and invariance considerations, and even conservation laws, played undoubtedly an important role in the thinking of the early physicists, such as Galileo and Newton, and probably even before then. However, these considerations were not thought to be particularly important and were articulated only rarely.

Integrable viscous conservation laws [PDF]

open access: yes, 2014
We propose an extension of the Dubrovin-Zhang perturbative approach to the study of normal forms for non-Hamiltonian integrable scalar conservation laws. The explicit computation of the first few corrections leads to the conjecture that such normal forms

Conservation Laws and Interactionist Dualism [PDF]

open access: yes, 2016
The Exclusion Argument for physicalism maintains that since (1) every physical effect has a sufficient physical cause, and (2) cases of causal overdetermination are rare, it follows that if (3) mental events cause physical events as frequently ...

Conservation laws for the classical Toda field theories

open access: yes, 1993
We have performed some explicit calculations of the conservation laws for classical (affine) Toda field theories, and some generalizations of these models.

Multi-Gear Bandits, Partial Conservation Laws, and Indexability

open access: yesMathematics, 2022
This paper considers what we propose to call multi-gear bandits, which are Markov decision processes modeling a generic dynamic and stochastic project fueled by a single resource and which admit multiple actions representing gears of operation naturally ...

Self-Adjointness, Symmetries, and Conservation Laws for a Class of Wave Equations Incorporating Dissipation

open access: yesAbstract and Applied Analysis, 2013
In this work, we study the nonlinear self-adjointness and conservation laws for a class of wave equations with a dissipative source. We show that the equations are nonlinear self-adjoint.

Integrability from an abelian subgroup of the diffeomorphism group

open access: yes, 2005
It has been known for some time that for a large class of non-linear field theories in Minkowski space with two-dimensional target space the complex eikonal equation defines integrable submodels with infinitely many conservation laws.
