The Stokes triangulation–seed correspondence conjecture

Let TT be a labeled Stokes triangulation of an orbifold (O,A)(\mathbf{O},\mathbf{A}). Consider a sequence of signed flips

T=μkN(εN)μk1(ε1)(T).T'=\mu_{k_N}^{(\varepsilon_N)}\circ\cdots\circ\mu_{k_1}^{(\varepsilon_1)}(T).

Let (B,x,y)(B,x,y) be a seed with B=B(T)B=B(T), and apply the same sequence of signed mutations:

(B,x,y)=μkN(εN)μk1(ε1)(B,x,y).(B',x',y')=\mu_{k_N}^{(\varepsilon_N)}\circ\cdots\circ\mu_{k_1}^{(\varepsilon_1)}(B,x,y).

Stokes triangulation–seed correspondence conjecture. We have T=TT=T' if and only if (B,x,y)=(B,x,y)(B',x',y')=(B,x,y). This conjecture asserts that the seed obtained from signed mutations records exactly whether the corresponding sequence of signed flips returns the Stokes triangulation to its initial state.
