Finite dimensional approximations for Hilbert space operators and applications in Quantum Mechanics
Eva A. Gallardo-Gutiérrez, Fernando Lledó, Laura Sáenz
In this work, we develop a unified framework for quasidiagonal and Følner-type approximations of linear operators on Hilbert spaces. These approximations (originally formulated for…

Boundedness, compactness and Schatten-class membership of weighted composition operators
Eva A. Gallardo-Gutiérrez, Romesh Kumar, Jonathan R. Partington
The boundedness and compactness of weighted composition operators on the Hardy space of the unit disc is analysed. Particular reference is made to the case when th…
