Atoms and associated spectral properties for positive operators on L^p

Jean-François Delmas, Kacem Lefki, Pierre-André Zitt

Inspired by Schwartz, Jang-Lewis and Victory, who study in particular generalizations of triangularizations of matrices to operators, we shall give for positive operators on Lebesg…
