Well-posedness for the Prandtl system without analyticity or monotonicity

David Gérard-Varet, Nader Masmoudi

Research output: Contribution to journalArticlepeer-review


It has been thought for a while that the Prandtl system is only well-posed under the Oleinik monotonicity assumption or under an analyticity assumption. We show that the Prandtl system is actually locally well-posed for data that belong to the Gevrey class 7/4 in the horizontal variable x. Our result improves the classical local well-posedness result for data that are analytic in x (that is Gevrey class 1). The proof uses new estimates, based on non-quadratic energy functionals.
