Shock Wave Formation Process for a Multidimensional Scalar Conservation Law
نویسندگان
چکیده
We construct a global smooth approximate solution to a multidimensional scalar conservation law describing the shock wave formation process for initial data with small variation. In order to solve the problem, we modify the method of characteristics by introducing “new characteristics”, nonintersecting curves along which the (approximate) solution to the problem under study is constant. The procedure is based on the weak asymptotic method, a technique which appeared to be rather powerful for investigating nonlinear waves interactions.

Remarks on the formation and decay of multidimensional shock waves
In this paper, we present a formula describing the formation and decay of shock wave type solutions in some special cases. In [1] and [2], in the quadratic and general cases of convex nonlinearity, we consider the process of formation of shock waves for scalar conservation laws in the one-dimensional case. Recall that, in the construction suggested in these papers, the key role is played by the...
متن کاملScaling Limits of Waves in Convex Scalar Conservation Laws Under Random Initial Perturbations
We study waves in convex scalar conservation laws under noisy initial perturbations. It is known that the building blocks of these waves are shock and rarefaction waves, both are invariant under hyperbolic scaling. Noisy perturbations can generate complicated wave patterns, such as diffusion process of shock locations. However we show that under the hyperbolic scaling, the solutions converge in...
متن کاملViscous Shock Wave Tracing, Local Conservation Laws, and Pointwise Estimates by Tai-ping Liu and Shih-hsien Yu
We introduce a new approach to decompose a system of viscous conservation laws with respect to each characteristic wave structures. Under this new decomposition, the global wave interactions of the system are reduced to coupling of nonlinear waves around constant states outside shock region and a scalar conservation law in the shock region to determine the behavior of local internal shock layer...
متن کاملDelta Shock Wave Formation in the Case of Triangular Hyperbolic System of Conservation Laws
We describe δ shock wave arising from continuous initial data in the case of triangular conservation law system arising from ”generalized pressureless gas dynamics model” (e.g. [12]). We use the weak asymptotic method [8, 9]. In this paper we investigate formation of δ-shock wave in the case of triangular system of conservation laws: ut + (f(u))x = 0, (1) vt + (vg(u))x = 0, (2) with continuous ...
متن کاملExistence and Uniqueness for Multidimensional Scalar Conservation Law with Discontinuous Flux
We prove existence and uniqueness of an entropy solution to a multidimensional scalar conservation law with discontinuous flux. The proof is based on the corresponding kinetic formulation of the considered equation and a ”smart” change of an unknown function.
