Title: Algebraic properties of the set of operators with 0 in the closure of the numerical range
Authors: Diogo, C.
Keywords: Numerical range
Issue Date: 2015
Publisher: Element d.o.o.
Abstract: Sets of operators which have zero in the closure of the numerical range are studied. For some particular sets T ⊆ B(H ), we characterize the set of all operators A ∈ B(H ) such that 0 ∈ W(TA) for every T ∈ T .
