Duality for noncommutative frames
Karin Cvetko-Vah, Jens Hemelaer, Lieven Le Bruyn
We characterize the left-handed noncommutative frames that arise from sheaves on topological spaces. Further, we show that a general left-handed noncommutative frame arises fro…
Noncommutative Frames Revisited
Karin Cvetko-Vah, Jens Hemelaer, Jonathan Leech
In this note, we correct an error in arXiv:1702.04949 by adding an additional assumption of join completeness. We demonstrate with examples why this assumption is necessary, and di…
Regular Antilattices
Karin Cvetko-Vah, Michael Kinyon, Jonathan Leech +1
Antilattices for which the Green's equivalences , , and are all congruence…
Skew lattices and set-theoretic solutions of the Yang-Baxter equation
Karin Cvetko-Vah, Charlotte Verwimp
In this paper we discuss and characterize several set-theoretic solutions of the Yang-Baxter equation obtained using skew lattices, an algebraic structure that has not yet been rel…
Towards a skew lattice approach to quantum (computational) logic
Karin Cvetko-Vah
In quantum mechanics, each observable is assigned a collection of projections. Two observables are compatible (can be measured simultaneously) if and only if any two projections th…
