Local Spectrum of a Family of Operators

Simona Macovei

Full-text: Open access


‎Starting from the classic definitions of resolvent set and spectrum‎ ‎of a linear bounded operator on a Banach space‎, ‎we introduce the‎ ‎local resolvent set and local spectrum‎, ‎the local spectral space and‎ ‎the single-valued extension property of a family of linear bounded‎ ‎operators on a Banach space‎. ‎Keeping the analogy with the classic‎ ‎case‎, ‎we extend some of the known results from the case of a linear‎ ‎bounded operator to the case of a family of linear bounded operators‎ ‎on a Banach space.
