半经典分析与伪谱

Semi-classical Analysis and Pseudospectra

E. B. Davies

摘要:

证明了非自伴算子的一个近似谱定理,并研究了它在二阶微分算子半经典极限中的应用。这导致了扭曲的FBI变换的构造。我们还研究了半经典极限中伪谱与边界条件之间的关系。

英文摘要:

We prove an approximate spectral theorem for non-self-adjoint operators and investigate its applications to second order differential operators in the semi-classical limit. This leads to the construction of a twisted FBI transform. We also investigate the connections between pseudospectra and boundary conditions in the semi-classical limit.
