Local Well-posedness of Free Boundary Problems for the Euler--Monge--Amp\`ere Equations
We study the free-boundary Euler--Monge--Amp\`ere system as a conservative relaxation of ideal incompressible fluid motion. The force is determined on the actual fluid domain by a Monge--Amp\`ere equation coupled to a nonlinear boundary condition. For each fixed relaxation parameter, we establish local well-posedness f...
