Abstract We propose two new direct methods for proving partial regularity of solutions of nonlinear elliptic or parabolic systems. The methods are based on two similar interpolation inequalities for solutions of linear systems with constant coefficient. The first results from an interpolation inequality of L p {L^{p}} norms in combination with an L p {L^{p}} estimate with low exponent p > 1 {p>1} . For the second, we provide a functional-analytic proof, that also sheds light upon the A-harmonic approximation lemma of Duzaar and Steffen. Both methods use a Caccioppoli inequality and avoid higher integrability. We illustrate the methods in detail for the case of a quasilinear elliptic system.
提出了两种新的直接证明非线性椭圆型或抛物型系统解的部分正则性的方法。该方法基于常系数线性系统解的两个类似插值不等式。第一个结果是由L p {L^{p}}范数与L p {L^{p}}低指数p> {p>1}估计相结合的插值不等式得到的。其次，我们提供了一个泛函解析证明，这也揭示了Duzaar和Steffen的a调和近似引理。两种方法都使用了Caccioppoli不等式，避免了较高的可积性。对于拟线性椭圆系统，我们详细地说明了这些方法。
