Shappiro's Epistemic Arithmetic #734

@SnO2WMaN

Description

@SnO2WMaN

大雑把に言って,言語 L_arithBox を入れて様相に関して S4 にしたものをShappiroのEpistemic Arithmetic EA と呼ぶ.

Note

Gödel変換を $(\forall x. \varphi)^g \mapsto \Box \forall x. \varphi^g$ および $(\exists x.\varphi)^g \mapsto \exists x. \varphi^g$ と定めると,Heyting Arithmetic HAEA はmodal companionを成す.

まずはとりあえずHeyting算術 #702 を作る必要があるが.
