Abstract:We prove that for a given strictly increasing initial datum in Ck, the solution of the initial value problem is piecewise Ck smooth except for flux functions of nonconvex conservation laws in a certain subset of Ck+1 of first category, defined in the range of the initial datum.
Keywords:piecewise smooth solutions  noncovex conservation laws  a set of first category
