comment Eigenvector of a linear combination of operators is an eigenvector of each operator
The canonical commutation relations are $[a_i,a_j]=[a^*_i,a^*_j]=0, [a_i,a^*_j]=\delta_j^i$, Mr. @Lewis.

The $a$'s are cube roots of unity, Mr. @Bennet. Equality is not the same as congruence.

I'm sorry. The $a$'s are not integers. They are on the unit circle.

comment Game theoretical approach to other branches of mathematics
Game theory is important in descriptive set theory. In particular Choquet games and Banach-Mazur games are applied. Try Kechris' Classical Descriptive Set Theory. Dynamic games are used in optimal control.

comment Realization (in the sense of homotopy coherent nerve) of $\partial\Delta^n$
What does $\mathfrak{C}\Delta^n(i, j)$ stand for? What about $(\Delta^1)^{(j-i-1)}$ and $\partial\Delta^n(k, n)$?
