Toeplitz operators on some function spaces
Chafiq Benhida, George R. Exner, Ji Eun Lee +1
We reconsider studies of Toeplitz operators on function spaces (the weighted Bergman space, the generalized derivative Hardy space) and the H-Toeplitz operators on the Bergman spac…

Signed representing measures (Berger-type charges) in subnormality and related properties of weighted shifts
Chafiq Benhida, Raúl E. Curto, George R. Exner
In the study of the geometrically regular weighted shifts (GRWS) -- see [5] -- signed power representing measures (which we call Berger-type charges) played an important role. Moti…
