N2 - In 1994, Lions, Perthame and Tadmor conjectured the maximal smoothing effect for multidimensional scalar conservation laws in Sobolev spaces. For strictly smooth convex flux and the one-dimensional case, we detail the proof of this conjecture in the framework of Sobolev fractional spaces Ws,1, and in fractional BV spaces: BVs. The BVs smoothing effect is more precise and optimal. It implies the optimal Sobolev smoothing effect in Ws,1 and also in Ws,p with the optimal p=1/s. Moreover, the proof expounded does not use the Lax–Oleinik formula but a generalized one-sided Oleinik condition.
