A second order explicit finite element scheme to multi-dimensional conservation laws and its convergence. (English) Zbl 0999.65105
Summary: A second-order explicit finite element scheme is, given for the numerical computation to multi-dimensional scalar conservation laws. $$L^p$$-convergence to entropy solutions is proved under some usual conditions. For two-dimensional problems, uniform mesh, and sufficiently smooth solutions a second-order error estimate in $$L^2$$ is proved under a stronger condition, $$\Delta t\leq Ch^{4/3}$$.
