Functional Calculi, Positivity, and Convolution of Matrices
Javad Mashreghi, Mostafa Nasri, Prateek Kumar Vishwakarma
Convolution admits a natural formulation as a functional operation on matrices. Motivated by the functional and entrywise calculi, this leads to a framework in which convolution de…
Weighted composition operators on de Branges-Rovnyak spaces
Emmanuel Fricain, Muath Karaki, Javad Mashreghi +1
In this paper, we characterize the boundedness and the compactness of weighted composition operators acting on a de Branges-Rovnyak space , where the symbol is a…
Infinitely supported harmonically weighted Dirichlet spaces which are de Branges Rovnyak spaces
Carlo Bellavita, Eugenio Dellepiane, Andreas Hartmann +1
Harmonically weighted Dirichlet spaces and de Branges_Rovnyak spaces are two fundamental structures in analytic function theory exhibiting rich and…
Schauder Basis with Finite Blaschke Products
Emmanuel Fricain, Javad Mashreghi, Mostafa Nasri +1
We construct a Schauder basis for the space , the space of holomorphic functions on the closed unit disk, consisting entirely of finite Blaschke products. The expan…
