Similarities of subspace lattices in Banach spaces
Janko BraÄiÄ, Marko KandiÄ
A collineation of a subspace lattice $\fL$ in a complex Banach space $\eX$ is an invertible operator on $\eX$ with the property that the image $S\eM$ of a subspace $\eM$ belong…

Positive self-commutators of positive operators
Roman DrnovÅ¡ek, Marko KandiÄ
We consider a positive operator on a Hilbert lattice such that its self-commutator is positive. If is also idempotent, then it is an orthogonal projecti…

Artinian and Noetherian vector lattices
Marko KandiÄ, Mark Roelands, Marten Wortel
In this paper, we study Artinian and Noetherian properties in vector lattices and provide a concrete representation of these spaces. Furthermore, we describe for which Archimedean…
