    review text
    Among non-normal operators, the class of hyponormal operators is distinguished by a rich phenomenology, mostly due to a singular integral model and to majorization techniques. Quite a long time ago it was realized that same majorization techniques can be applied to wider classes of operators, such as \(p\)-hyponormal, log-hyponormal, paranormal, and so on.
