On -based orthomodular dynamic algebras

Jan Paseka, Juanda Kelana Putra, Richard Smolka

This paper establishes a categorical equivalence between the category of complete orthomodular lattices and the category of -b…

Quantales carrying ortholattice structure

Michal Botur, David Kruml, Jan Paseka

This paper investigates the intersection of residuated structures from many-valued logic and orthomodular lattices from quantum logic. We explore whether non-Boolean structures can…

Axiomatising the dagger category of complex Hilbert spaces

Jan Paseka, Thomas Vetterlein

We axiomatise the dagger category of complex Hilbert spaces and bounded linear maps, using exclusively purely categorical conditions. Our axioms are chosen with the aim of an easy…

Dagger categories of orthosets and the complex Hilbert spaces

Jan Paseka, Thomas Vetterlein

An orthoset is a non-empty set together with a symmetric binary relation and a constant such that for any , and for any . M…

Characterisation of quadratic spaces over the Hilbert field by means of the orthogonality relation

Miroslav Korbelář, Jan Paseka, Thomas Vetterlein

An orthoset is a set equipped with a symmetric, irreflexive binary relation. With any (anisotropic) Hermitian space , we may associate the orthoset , consisting of…

Categories of orthosets and adjointable maps

Jan Paseka, Thomas Vetterlein

An orthoset is a non-empty set together with a symmetric and irreflexive binary relation , called the orthogonality relation. An orthoset with 0 is an orthoset augmented wit…
