## Convergence of an upstream finite volume scheme for a nonlinear hyperbolic equation on a triangular mesh.(English)Zbl 0801.65089

The following nonlinear hyperbolic problem in two-dimensional space is considered (1) $$u_ t (x,t) + \text{div} (v(x,t) f(u(x,t))) = 0$$, $$x \in \mathbb{R}^ 2$$, $$t \in\mathbb{R}_ +$$, $$\text{div} v(x,t) = 0$$, $$\sup_{x,t} | v(x,t) | < \infty$$. An explicit Euler scheme is used for the time discretization of (1) and a triangular mesh for the spatial discretization. Under a usual stability condition,the convergence of the solution obtained by an upstream finite volume scheme towards the unique entropy weak solution of (1) is proved.
