证明了二重度量测度空间上p-Dirichlet能量泛函的拟极小族关于变指数p的稳定性结果。此外,我们证明了具有固定边界数据的拟极小的上梯度的整体更高的可积性,只要边界数据属于一个稍微好一点的牛顿空间。
We prove a stability result, with respect to the varying exponent p, for a family of quasiminimizers of the p‐Dirichlet energy functional on a doubling metric measure space. In addition, we prove global higher integrability for upper gradients of quasiminimizers with fixed boundary data, provided that the boundary data belong to a slightly better Newtonian space.
