Abstract
It is still unknown whether the inverse of an invertible k -paranormal operator is normaloid, and so whether a k -paranormal operator is totally hereditarily normaloid. We provide sufficient conditions for the inverse of an invertible k -paranormal operator to be k -paranormal. Mathematics subject classification (2010): Primary 47A45, Secondary 47B20.
