We prove a local higher integrability result for the spatial gradient of weak solutions to doubly nonlinear parabolic systems whose prototype is with parameters and and . In this paper, we are concerned with the ranges and . A key ingredient in the proof is an intrinsic geometry that takes both the solution and its spatial gradient into account.
我们证明了一类双重非线性抛物型系统弱解的空间梯度的局部更高可积性结果,其原型为 ,参数为 、 和 。在本文中,我们关注的范围是 和 。证明中的一个关键要素是一种将解 及其空间梯度 都考虑在内的内在几何结构。
