Relaxation of the incompressible porous media equation
Relaxation of the incompressible porous media equation
L SZÉKELYHIDI J.A.-It was shown recently by Córdoba, Faraco and Gancedo in [1] that the 2D porous media equation admits weak solutions with compact support in time.The proof, based on the convex integration framework developed for the incompressible Euler equations in [4], uses ideas from the theory of laminates, …
