The Category of Node-And-Choice Forms for Extensive-Form Games

No 20165, University of Western Ontario, Departmental Research Report Series from University of Western Ontario, Department of Economics

Abstract: It would be useful to have a category of extensive-form games whose isomorphisms specify equivalences between games. Toward this goal, Streufert (2016) introduced the category of node-and-choice preforms, where a "preform" is a rooted tree together with choices and information sets. This paper takes another step: It introduces the category of node-and-choice forms, where a "form" is a preform augmented with players. In addition, it derives some consequences of the category's morphisms and provides a characterization of the category's isomorphisms.
