We consider quasilinear elliptic systems in divergence form. In general, we cannot expect that weak solutions are locally bounded because of De Giorgi’s counterexample. Here we assume that off-diagonal coefficients have a “butterfly support”: this allows us to prove local boundedness of weak solutions.

蝶形支持非对角系数和拟线性椭圆系统解的有界性

我们考虑散度形式的拟线性椭圆系统。一般来说,我们不能指望弱解是局部有界的,因为 De Giorgi 的反例。在这里,我们假设非对角系数具有“蝴蝶支持”:这使我们能够证明弱解的局部有界性。
