Using this, a result which implies the main theorem of Abramovich, Aliprantis and Burkinshaw [J. Funct. Anal. 115 (1993) 418-424] is also given.eninfo:eu-repo/semantics/closedAccesspositive operatorsemigroupinvariant subspacequasinilpotentweak quasinilpotentInvariant subspaces for positive operators on locally convex solid Riesz spacesArticle10.1016/S0019-3577(07)80030-91834174202-s2.0-38149040060Q2WOS:000252195500005Q4
