On the conservation laws of PDEs

Reports on Mathematical Physics, 1988
The covariance of methods for obtaining conservation laws for nonlinear partial differential equations is studied [the second author, Riv. Nuovo Cim. 5, No.4, 1-122 (1982; see the review above) and \textit{A. M. Vinogradov}, J. Math. Anal. Appl. 100, 41-129 (1985; Zbl 0548.58015)].

On the optimization of a conservation law

Calculus of Variations and Partial Differential Equations, 2004
Consider the Cauchy problem for a conservation law and assume that an integral functional on its solution is defined. In this note we obtain an Euler-Lagrange equation for the stationary points of this functional. An application to the optimal management of traffic flows is considered.

On Stability of Conservation Laws

SIAM Journal on Mathematical Analysis, 1999
We consider the Cauchy problem for systems of PDEs of the general form $$ u_t=P_0u + \eps_1P_1u +\eps_2 Q(u) + \sum_j D_j F_j(x,t), \quad u=u(x,t). $$ Here $P_0$ has constant coefficients. The terms $\eps_1 P_1u$ and $\eps_2 Q(u)$ describe linear and nonlinear perturbations, respectively, and $\textstyle\sum_j D_j ...
