Consider the Cauchy problem for a hyperbolic
$n\times n$ system of conservation laws in one space
dimension:
$u_t + f(u)_x = 0$, $u(0,x)=\bar u (x).$
$(CP)$
Relying on the existence of a continuous semigroup of solutions, we prove that the
entropy admissible solution of $(CP)$ is unique within
the class of functions $u=u(t,x)$
which have bounded variation along a
suitable family of space-like curves.
