Using this, a result which implies the main theorem of Abramovich, Aliprantis and Burkinshaw [J. Funct. Anal. 115 (1993) 418-424] is also given.en-USpositive operatorsemigroupinvariant subspacequasinilpotentweak quasinilpotentpozitif operatöryarıgrupdeğişmeyen alt uzayyarınilpotentzayıf yarınilpotentInvariant subspaces for positive operators on locally convex solid Riesz spacesArticle2521955000052521955000052-s2.0-381490400602-s2.0-38149040060
