Abstract

In this article, we study a class of fully nonlinear double-divergence systems with free boundaries associated with a minimization problem. The variational structure of the Hessian-dependent functional plays a fundamental role in proving the existence of the minimizers and then the existence of the solutions for the system. In addition, we establish improvements in integrability for the equation in the double-divergence form. Consequently, we improve the regularity for the fully nonlinear equation in Sobolev and Hölder spaces.

一类完全非线性双散度系统的两相自由边界问题

本文研究了一类具有自由边界的完全非线性双散度系统的最小化问题。Hessian-dependent泛函的变分结构在证明系统极小值的存在性和解的存在性方面起着重要的作用。此外，我们建立了双散度形式方程可积性的改进。因此，我们改进了Sobolev和Hölder空间中全非线性方程的正则性。
