Quasireducible Operators,That is, if and only if there exists a nonscalar . in {.}′ ⋂ {.*}′, where {.}′ denotes the commutant of .. Equivalently, . is reducible if and only if both . and . lie in {.}′ for some nonscalar operator .. Quasireducibility was recently introduced in [34].

Spectral Properties,One of the fundamental theorems of (linear) functional analysis, namely, the Open Mapping Theorem, says that . (a mapping is . if it maps open sets onto open sets). A crucial corollary is the Inverse Mapping Theorem (see e.g., [32, p. 228]).
