一类复系数退化二阶算子的局部可解性

On the Local solvability of a class of degenerate second order operators with complex coefficients

Serena Federico, Alberto Parmeggiani

摘要:

研究了一类具有多重特征的算子的局部可解性。本文所考虑的算子类是对文献[9]中所研究的算子类的补充和推广,在本文中,我们考虑了文献[9]中所没有的复系数算子的一些情形。这里考虑的一类算子理想地包括退化抛物型算子和薛定谔型算子。我们将给出局部可解性定理。在一般情况下,一个$L^2$局部可解性,但也有局部可解性的情况下,更好的Sobolev正则性。

英文摘要:

We study the local solvability of a class of operators with multiple characteristics. The class considered here complements and extends the one studied in [9], in that in this paper we consider some cases of operators with complex coefficients that were not present in [9]. The class of operators considered here ideally encompasses classes of degenerate parabolic and Schrödinger type operators. We will give local solvability theorems. In general, one has $L^2$ local solvability, but also cases of local solvability with better Sobolev regularity will be presented.
