In this paper we prove sufficient conditions for the Fredholm property of a non-smooth pseudodifferential operator $P$ which symbol is in a H\"older space with respect to the spatial variable. As a main ingredient for the proof we use a suitable symbol-smoothing.

非光滑伪微分算子的 Fredholm 性质

在本文中,我们证明了非光滑伪微分算子 $P$ 的 Fredholm 性质的充分条件,其中符号位于相对于空间变量的 H\"旧空间中。作为证明的主要成分,我们使用合适的符号-平滑。
