Characterization of 2-summing operators in Krein spaces
Keywords:
Krein space, inner product space, bounded linear operator, absolutely 2-summing operatorsAbstract
Let A be a bounded linear operator and absolutely 2-summing on a Krein space K, with the canonical decomposition. In this paper, we prove that the elements in the matrix decomposition of A are absolutely 2-summing. We characterize 2-summing operators in Krein spaces using a fixed fundamental decomposition.
