Cohyponormal Composistion Operators on The Hardy Space and Hyponormal Toeplitz Operators on the Harmonic Bergman Space
SADRAOUI, HOUCINE . 2017
.We study cohyponormality of composition operators with a fractional symbol on the Hardy space and on weighted Bergman spaces .We also caracterize hyponormal Toeplitz operators with a harmonic symbol on the harmonic Bergman space
Hyponormality on the annulus with a logarithmic weight is studied. Necessary conditions , which consist of derivative inequalities on the boundary of the annulus, are shown. A consequence on…

I give a sufficient condition for hyponormality when the analytic part is a monomial and also generalize a known necessary condition for hyponormality (in the case of a harmonic symbol) to…
