Flip cycles in plabic graphs

Abstract Planar bicolored (plabic) graphs are combinatorial objects introduced by Postnikov to give parameterizations of the positroid cells of the totally nonnegative Grassmannian $$\text {Gr}^{\ge 0}(n,k)$$Gr≥0(n,k). Any two plabic graphs for the same positroid cell can be related by a sequence o...
