Isometric rigidity of complete Pick algebras on monomial varieties
Hamidul Ahmed, B. Krishna Das, Chaman Kumar Sahu
We establish a geometric rigidity theorem for a class of monomial varieties in finite-dimensional unit balls. Every ball automorphism mapping one such variety onto another is unita…
de Branges-Rovnyak spaces which are complete Nevanlinna-Pick spaces
Hamidul Ahmed, B. Krishna Das, Samir Panja
We consider de Branges-Rovnyak spaces of a considerably large class of reproducing kernel Hilbert spaces and find a characterization for them to be complete Nevanlinna-Pick spaces.…
Determining sets for holomorphic functions on the symmetrized bidisk
B. Krishna Das, P. Kumar, H. Sau
This paper studies the determining sets for analytic functions from the symmetrized bidisk into the open unit disk in . It relates the idea to the uniqueness of the solu…
Algebraic Properties of Toeplitz operators on the symmetrized polydisk
Bata Krishna Das, Haripada Sau
This paper introduces the classically successful theory of Toeplitz operators on the Hardy space over the unit disk to a new domain in -- the symmetrized polydisk.
