Code

• DubrovinDynamics
  This shows the evolution of eigenvalues in the spectrum of the truncated Dubrovin operator of some Grassmannians, as one deforms the bulk parameters.
• Posetroids
  This generates a list of all positroid strata in a given Grassmannian, together with the partial order on them induced by Zariski closure.
• ClusterExplorer
  This is a random walk on the exchange graph of the cluster structure of the top positroid strata. These spaces are believed to support Landau-Ginzburg models for Grassmannians, and the walk allows to study the Laurent polynomials describing the potential in each chart.
