One-parameter Semigroups of Positive Operators

This volume develops the structural theory of one‑parameter semigroups of positive operators on ordered Banach spaces, addressing the fundamental problem of characterizing their generators, spectral properties, and asymptotic behavior. Such semigroups form a central analytical framework for models arising in partial differential equations, probability theory, ergodic theory, and mathematical physics.

Since its first publication in 1986, the book has become a foundational reference, offerin...
