Trigger

旧HP Problems 5.0.2から移住する公開問題。旧HPは Games as recursive coalgebras とJoyalのgames and strategiesを参照していた。created は前者の論文の初公開日を代理値とし、正確な着想日は不明。

Idea

Is there a double category Games\mathbf{Games} whose vertical part is the category of games as recursive coalgebras and whose horizontal part is, in some sense, Joyal's compact closed category of games and strategies?

A bridge between the recursive-coalgebraic and strategy-categorical views of games.

Goal

旧原文にあるvertical partとhorizontal partを持つdouble categoryが存在するかを明らかにする。

Personal context

旧タグは double category、recursive coalgebra、Joyal games。旧一覧以後の進展はこの移住では未確認であり、棚卸し待ちとして status: dormant とする。
