We show that the results for the supercyclicity of hy- ponormal operators described in [8] remain true for A-hyponormal operators. Also, we show that every A-hyponormal operators is A-power regular. Also we show that an A-hyponormal operators have a nontrivial hyperinvariant subspace.enA-hyponormalA-normalA-power regularsemi-inner productssupercyclic operatorsinvariant set.Intervention
