An operator \(T\) is said to be log-hyponormal if \(T\) is invertible and \(\log T^*T \ge \log TT^*\), and \(p\)-paranormal for \(p > 0\) if \(\||T|^p U |T|^p x\| \ge \||T|^p x\|^2\) for every unit vector \(x\), where the polar decomposition of \(T\) is \(T = U|T|\). We show that \(T\) is log-hyponormal if and only if \(T\) is invertible and \(p\)-paranormal for all \(p > 0\).
