Add to ORKGIn this paper we show that if two operators A and B are quasi-invertible then AB and BA are also quasi-similar. We also show that if two operators and are isometric is consistent in invertibility under further hypothesis. AMS subject classification: 47B47, 47A30, 47B20 Keywords and phrases: Quasi-similarity, quasi-affinity and consistent in invertibility
