Commutants and spectral properties of operators in hilbert spaces
(School of mathematics, 2012-09)This thesis is devoted to the study of commutants and spectral properties of operators in Hilbert spaces. This is done via the following operator equations: AB =λBA, where λ ∈ℂ, AX = XB and AXB = X. In the operator ...
