Trigger

chatgptでadditive subtraction Nim (S={s_1,s_2,s_1+s_2}) のsink–wall dualityを検討し,(mathbb Z/pmathbb Z)上のnimber列をmex operatorとrev-mex involutionの力学系として扱う案が生じた.既存のgame differential構造 Differential structures of games から派生する具体問題である.

Idea

[
X={0,1,2,3}^{mathbb Z/pmathbb Z}
]
上に
[
(M_Sf)(x)=operatorname{mex}{f(x-s)mid sin S}
]
を定める.nimber involution (sigma) を
[
sigma(0)=2,quad sigma(2)=0,quad sigma(1)=1,quad sigma(3)=3
]
とし,reflection/translationを組み込んだ
[
(J_bf)(x)=sigma(f(-b-x))
]
を考える.sink–wall予想
[
v_{mathrm{wall}}([x]_p)

sigma!left(v_{mathrm{sink}}([-s_2-x]_p)
ight)
]
を,(M_S)と(J_b)のintertwining relationまたはtime-reversal symmetryとして導出できるかを問う.

Goal

個別のfloor formulaを,有限状態dynamical systemのreversibility/conjugacyとして説明する.まずoperator identityが全(X)で成り立つのか,sink/wall boundary conditionが定めるinvariant subset上だけで成り立つのかを切り分ける.
