Minimal Length Maximal Green Sequences
Maximal green sequences are important objects in representation
theory, cluster algebras, and string theory. It is an open problem to
determine what lengths are achieved by maximal green sequences of a
quiver. We use the combinatorics of surface triangulations to address
this problem. Our main result is a formula for the length of minimal
length maximal green sequences of quivers defined by triangulations of
an annulus or a punctured disk.
