The invariant subspace problem for absolutely p-summing operators in Krein spaces

Research output: Contribution to journalArticle


Let [InlineEquation not available: see fulltext.], and let T be a bounded linear operator defined on a Krein space [InlineEquation not available: see fulltext.]. We prove the existence of a non-positive subspace [InlineEquation not available: see fulltext.] of [InlineEquation not available: see fulltext.] invariant under T with the assumption that T is absolutely p-summing with some further conditions imposed on it.
