New characterizations of subclasses of A-selfadjoint, A-normal and A-partial isometry operators on semi-Hilbertian spaces

Key Points

• The aim is to characterize subclasses of A-selfadjoint, A-normal, and A-partial isometry operators.
• Utilized arithmetic-geometric mean inequality to characterize subclasses.
• Presented operator inequalities associated with these subclasses.
• Described specific properties of the characterized subclasses of operators.
