An ill-posed Cauchy problem for a hyperbolic system in two space dimensions. (English) Zbl 1114.35123
The author first constructs the solution of the Cauchy problem for a scalar conservation law. Then he presents examples showing that under exactly the same assumptions that guarantee the existence and uniqueness of solutions in the one-dimensional case, in two space dimensions the Cauchy problem is not well posed.
