我们证明了二维和三维多凸函数极小值的存在性、唯一性和正则性,这对应于保测映射的 H1 投影。我们的结果基于拉格朗日乘子的小性,引入了关于最小化器唯一性的新标准。无需对压力的二阶导数进行估计即可获得唯一的全局最小化器。作为一个应用,我们构建了一个最小化运动方案来构建短时间间隔的纳维-斯托克斯方程(NSE)的 Lr 解。
We prove the existence, uniqueness, and regularity of minimizers of a polyconvex functional in two and three dimensions, which corresponds to theH1-projection of measure-preserving maps. Our result introduces a new criteria on the uniqueness of the minimizer, based on the smallness of the lagrange multiplier. No estimate on the second derivatives of the pressure is needed to get a unique global minimizer. As an application, we construct a minimizing movement scheme to constructLr-solutions of the Navier–Stokes equation (NSE) for a short time interval.
