Rubén A. Martínez Avendaño, Higher-rank numerical range in infinite-dimensional Hilbert space


Abstract


In this paper we calculate the higher-rank numerical range, as defined by Choi, Kribsand.Zyczkowski, of selfadjoint operators and of nonunitary isometries on infinite-dimensionalHilbert space.
