Dirichlet-type spaces on the unit ball and joint 2-isometries
Sameer Chavan, Rajeev Gupta, Md. Ramiz Reza
We obtain a formula that relates the spherical moments of the multiplication tuple on a Dirichlet-type space to a complex moment problem in several variables. This can be seen as t…

Analytic m-isometries and weighted Dirichlet-type spaces
S. Ghara, R. Gupta, Md. R. Reza
Corresponding to any -tuple of semi-spectral measures on the unit circle, a weighted Dirichlet-type space is introduced and studied. We prove that the operator of multiplica…
