Quivers and moduli spaces of pointed curves of genus zero
Algebraic Combinatorics, Volume 4 (2021) no. 1, pp. 89-124.

We construct moduli spaces of representations of quivers over arbitrary schemes and show how moduli spaces of pointed curves of genus zero like the Grothendieck–Knudsen moduli spaces M ¯ 0,n and the Losev–Manin moduli spaces L ¯ n can be interpreted as inverse limits of moduli spaces of representations of certain bipartite quivers. We also investigate the case of more general Hassett moduli spaces M ¯ 0,a of weighted pointed stable curves of genus zero.
