Shadowing phenomenon for composition operators on the Hardy space
Artur Blois, Ben-Hur Eidt, Paulo Lupatini +1
Let be a holomorphic self-map of the open unit disk In this article, we study the shadowing phenomenon for composition operators on the Hardy spac…
Relative ultragraph algebras and infinite interval maps
Ben-Hur Eidt, Daniel Gonçalves, Danilo Royer
In this paper, we introduce the notion of relative ultragraph algebras and extend classical injectivity criteria for representations, particularly those arising from branching syst…
Beurling and Model subspaces invariant under a universal operator
Ben Hur Eidt, S. Waleed Noor
In this article, we characterize the Beurling and Model subspaces of the Hardy-Hilbert space invariant under the composition operator , where…
Representations of C*-algebras of row-countable graphs and unitary equivalence
Ben hur Eidt, Danilo Royer
In this article we show that there are branching systems (which induce representations of the graph algebra ) associated to each row-countable graph . For row-countable…
