On Almost Interval Preserving Linear Operators

Siberian Mathematical Journal, 2022
In this paper, the author obtained an analogous description of \(AM\)-compact and compact almost interval preserving linear operators in quasi-Banach lattices. She established one structural property of almost interval preserving operators which is in its own right.

Invertibility of linear f-order preservers

Journal of Mathematical Sciences, 2006
The notion of \(f\)-ordering on the matrix set \(M_{m,n}({\mathbb C})\) over the field of complex numbers \({\mathbb C}\) was defined by \textit{J. Hauke, A. Markiewicz} and \textit{T. Szulc} [Linear Algebra Appl. 332--334, 437--445 (2001; Zbl 0982.15027)] in the following way. Let \(f:[0,\infty)\to [0,\infty]\) be a bijective function satisfying \(f(0)

Eigenvectors of Order-Preserving Linear Operators

Journal of the London Mathematical Society, 1998
Summary: Suppose that \(K\) is a closed, total cone in a real Banach space \(X\), that \(A: X\to X\) is a bounded linear operator which maps \(K\) into itself, and that \(A'\) denotes the Banach space adjoint of \(A\). Assume that \(r\), the spectral radius of \(A\), is positive, and that there exist \(x_0\neq 0\) and \(m\geq 1\) with \(A^m(x_0)= r^m ...
