Promonads and String Diagrams for Effectful Categories (Román, 2022)

Last updated Jul 23, 2024

Effectful program in string diagrammatic notation and arrow-do notation.

PhotoAbstract. 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. We show that effectful categories are pseudomonoids in a monoidal bicategory of promonads with a suitable tensor product.
