Q: Is a local system on a surface determined by simple closed loops?

Josh LamLet $\Sigma$ be a closed oriented topological surface of genus $g\geq 2$, and let $\mathfrak{X}_n$ denote the $\mathrm{SL}_n$-character variety of $\pi_1(\Sigma)$, i.e. $$ \mathfrak{X}_n= \mathrm{Hom}(\pi_1(\Sigma), \mathrm{SL}_n)//\mathrm{SL}_n. $$ So each point $p\in \mathfrak{X}_n$ corresponds...
