Irreducible Semigroups of Positive Operators on Banach Lattices

Niushan Gao, Vladimir G. Troitsky

The classical Perron-Frobenius theory asserts that an irreducible matrix $A$ has cyclic peripheral spectrum and its spectral radius $r (A)$ is an eigenvalue corresponding to a posit…

On Commuting and Semi-commuting Positive Operators

Niushan Gao

Let $K$ be a positive compact operator on a Banach lattice. We prove that if either $[K >$ or $< K]$ is ideal irreducible then $[K >=< K] = L_{+} (X) \cap K^{'}$ . We also establish the Perron…

Extensions of Perron-Frobenius Theory

Niushan Gao

The classical Perron-Frobenius theory asserts that for two matrices $A$ and $B$ , if $0 \leq B \leq A$ and $r (A) = r (B)$ with $A$ being irreducible, then $A = B$ . This was recently exten…
