Subject:
math and topological boundary of the spectrum of an operator
Language:
English
Description:
It is well-known that the topological boundary of the spectrum of an operator is contained in the approximate point spectrum. We show that the one-sided version of this result is not true. This gives also a negative answer to a problem of Schmoeger.
