Hilbert space theory and operator algebras provide a robust framework for analysing linear operators and their spectral properties, which are pivotal in both pure and applied mathematics. Hilbert ...
Operator algebras lie at the heart of functional analysis, providing a framework for studying rings of bounded operators on Hilbert and Banach spaces. Key examples include C*-algebras—norm-closed ...
