String Diagrams for Premonoidal Categories (Román, 2023)

string-diagrams-for-premonoidal-categories

Abstract. Premonoidal and Freyd categories are both generalized by non-cartesian Freyd categories: effectful categories. We construct string diagrams for effectful categories in terms of the string diagrams for a monoidal category with a freely added object.
