'Compositionality' - Journal

'Compositionality is a diamond open-access journal for research using compositional ideas, most notably of a category-theoretic origin, in any discipline. Compositionality describes and quantifies how complex things can be assembled out of simpler parts. Topics may concern foundational structures, an organizing principle, or a powerful tool. Example areas include but are not limited to: mathematics, computation, logic, physics, chemistry, engineering, linguistics, and cognition.

Compositionality is free of cost for both readers and authors (diamond open access). You can find our editorial policies here. Our first issue was published, under ISSN 2631-4444, in December 2019.'
