Cyclic nearly invariant subspaces for semigroups of isometries

Yuxia Liang, Jonathan R. Partington

In this paper, the structure of the nearly invariant subspaces for discrete semigroups generated by several (even infinitely many) automorphisms of the unit disc is described. As p…

Paired kernels and their applications

M. Cristina Câmara, Jonathan R. Partington

This paper considers paired operators in the context of the Lebesgue Hilbert space on the unit circle and its subspace, the Hardy space . The kernels of such operators, togeth…

Invariant subspaces of the Cesaro operator

Eva A. Gallardo-Gutierrez, Jonathan R. Partington, William T. Ross

This paper explores various classes of invariant subspaces of the classical Cesàro operator on the Hardy space . We provide a new characterization of the finite co-dimensi…

Paired operators and paired kernels

M. Cristina Câmara, André Guimarães, Jonathan R. Partington

This paper is concerned with paired operators in the context of the Lebesgue Hilbert space on the unit circle and its subspace, the Hardy space. By considering when such operators…

Boundedness and compactness of weighted composition operators and monomial operators

I. Chalendar, J. R. Partington

This paper characterises the boundedness and compactness of Agler--McCarthy monomial operators by reducing them to weighted composition operators and deriving explicit Carleson mea…

Admissibility of retarded diagonal systems with one-dimensional input space

Rafal Kapica, Jonathan R. Partington, Radoslaw Zawiski

We investigate infinite-time admissibility of a control operator in a Hilbert space state-delayed dynamical system setting of the form , wher…
