We show that, for first-order systems of conservation laws with a strictly convex entropy,in particular for the very simple so-called "inviscid" Burgers equation,it is possible to address the Cauchy problem by a suitable convex minimizationproblem, quite similar to some problems arising in optimal transport or variational mean-field game theory.In the general case, we show that smooth, shock-free, solutions can be recoveredon some sufficiently small interval of time. In the special situation of the Burgers equation, we furthershow that every "entropy solution" (in the sense of Kruzhkov)including shocks, can be recovered, for arbitrarily long time intervals.On montre que, pour les systemes du premier ordre de lois de conservation avec une en...
