[PDF][PDF] Hankel operators on Hilbert space

SC Power - Bulletin of the London Mathematical Society, 1980 - Citeseer
A famous inequality of D. Hilbert [70],[36] asserts that the matrix commonly known as Hilbert's
matrix, determines a bounded linear operator on the Hilbert space of square summable …

Schur products and matrix completions

VI Paulsen, SC Power, RR Smith - Journal of functional analysis, 1989 - Elsevier
We prove that a necessary and sufficient condition for a given partially positive matrix to have
a positive completion is that a certain Schur product map defined on a certain subspace of …

Weakly closed ideals of nest algebras

JA Erdos, SC Power - Journal of Operator Theory, 1982 - JSTOR
Let si be a nest algebra of operators on a Hilbert space H. We obtain description of all weakly
closed (two-sided) ideals of si; more generally, we des all weakly closed (two-sided)= s/-…

Free semigroupoid algebras

DW Kribs, SC Power - arXiv preprint math/0309394, 2003 - arxiv.org
Every countable directed graph generates a Fock space Hilbert space and a family of partial
isometries. These operators also arise from the left regular representations of free …
