Spectral theory for linear relations via linear operators
Dana Gheorghe, Florian Vasilescu · Pacific Journal of Mathematics · 2012
We develop a spectral theory for closed linear operators of the form T : D(T ) ⊂ X → X/ X 0 , where X is a complex Banach space and X 0 a closed vector subspace of it.This approach, essentially expressed in terms of linear operators, provides a better understanding of the spectral theory for closed linear relations.
