具有Friedrichs下界的自伴扩张

Self-adjoint extensions with Friedrichs lower bound

Matteo Gallone, Alessandro Michelangeli

摘要:

给出了一个简单的判别准则和一个构造性的方法来判别希尔伯特空间上下半有界对称算子的自伴扩张是否与Friedrichs扩张具有相同的下界.这个抽象的结果的应用程序,然后讨论了一些有指导意义的例子。

英文摘要:

We produce a simple criterion and a constructive recipe to identify those self-adjoint extensions of a lower semi-bounded symmetric operator on Hilbert space which have the same lower bound as the Friedrichs extension. Applications of this abstract result to a few instructive examples are then discussed.
