Add to ORKGIn the paper spectral theory and functional calculus of a pair of perturbed linear operators acting from one complex Banach space X to another Y is built. As distinct from the spectrum of a bounded operator acting in one space in this case the spectrum of a pair of operators (A,B) from X to Y can be for instance an unbounded set. Besides that the spectrum σ(A,B) can be an empty set. Mathematics Subject Classification: primary 47G99, secondary 47A9
