A "cell-entered" finite-difference scheme that uses two points for the inviscid ...We prove existence and L¹ stability (uniqueness) results for entropy weak solutions belonging to the class L¹ ∩ BV, while existence of at least one weak solution, satisfying a restricted set of entropy inequalities, is proved in the class L² ∩ L 4. Finally, we extend our results to a class of generalized Degasperis-Procesi equations. The 1D Burgers equation is solved using explicit spatial discretization (upwind and central difference) with periodic boundary conditions on the domain (0,2). The 2D case is solved on a square domain of 2X2 and both explicit and implicit methods are used for the diffusive terms. Dirichlet boundary conditions are used along the edges of the domain.solutions of Temple systems  of conservation laws. In , the authors proposed a viability framework for a Hamilton-Jacobi equation  corresponding to an integral form of the Burgers equation, which leads to lower semi-continuous solutions. One of the challenging features of the Burgers equation is the apparition of discontinuities in ...On the Hausdorff dimension of regular points of inviscid Burgers equation with stable initi 相关文档： Accessible Points in the Julia Sets of Stable Exponentials On the Hausdorff dimension of regular points of inviscid Burgers equation with stable initi 相关文档： Accessible Points in the Julia Sets of Stable Exponentials The origin of the method is based on the micro-model describing the movement of particles with prescribed velocities. We show that with the micro-model the inviscid Burgers' equation is solved in a weak sense. Numerical experiments have confirmed a low viscosity of the method: the solution is smeared by only one particle.The inviscid Burgers's equation is a flux-conservative partial differential equation, and is thus amenable to finite-volume methods, which are often used for numerically solving nonlinear, hyperbolic partial differential equations.
