Subdivisions of the spectra for cesaro, rhaly and weighted mean operators on c(0),c and l(P)
(SPRINGER INTERNATIONAL PUBLISHING AG, 2011)There are many different ways to subdivide the spectrum of a bounded linear operator; some of them are motivated by applications to physics (in particular, quantum mechanics). In this study, the relationship between the ... -
