Banach space theory, a cornerstone of functional analysis, investigates complete normed vector spaces and the continuous linear operators acting between them. Within this framework, operator ideals ...
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 ...
A theory on M-matrices is derived from simple results on inverse-positive linear operators. Some applications to eigenvalue theory and iterative procedures are discussed. The concepts occurring in ...
