Under suitable assumptions, we prove that the corresponding Cauchy problem admits a unique solution, which depends H\\\\\\\"older continuously on the initial data.\\nOur result applies in particular to the case where $f$ can be written in the form $f(t,x)\\\\doteq g\\\\big( u(t,x)\\\\big)$, for some function $g$ and some solution $u$ of a scalar conservation law, say $u_t+F(u)_x=0$. In turn, this yields the uniqueness and continuous dependence of solutions to a class of $2\\\\times 2$ strictly hyperbolic systems, with initial data in $\\\\L^\\\\infty$. %B Nonlinear Analysis 34 (1998) 637-652 %I Elsevier %G en_US %U http://hdl.handle.net/1963/3699 %1 606 %2 Mathematics %3 Functional Analysis and Applications %$ Submitted by Andrea Wehrenfennig (andreaw@sissa.it) on 2009-07-28T09:39:33Z\\nNo. of bitstreams: 1\\nbressan.pdf: 182373 bytes, checksum: 0eb82866d65dea9685ab7ff75c16c0d2 (MD5) %R 10.1016/S0362-546X(97)00590-7
