AbstractFor any θ<1/3 , we show that very weak solutions to the two-dimensional MongeAmpère equation with regularity C1,θ are dense in the space of continuous functions. This result is shown by a convex integration scheme involving a subtle decomposition of the defect at each stage. The decomposition diagonalizes the defect and, in addition, incorporates some of the leading-order error terms of the first perturbation, effectively reducing the required amount of perturbations to oneThis is a joint work with Jonas Hirsch and Dominik Inauen from Leipzig Univerisity.
