DESCRIPTION:Title : Cluster dualities and superpotentials for Grassmannian  Abstract: Marsh-Rietsch described a Landau-Ginzburg model for Grassmannians consisting of the complement of a particular anti-canonical divisor in a Langlands dual Grassmannian together with a superpotential expressed in terms of Pl¨ucker coordinates. On the other hand\, Grassmannians carry cluster structure which we can write down a superpotential from the work of Gross-Hacking-Keel-Kontsevich. A natural question is — are the two potentials the same or not? Together with Bossinger\, Magee\, and Najera-Chavez\, we identified the cluster structures of the two sides of the mirror Grassmannians and identified the Marsh-Rietsch and the Gross-Hacking-Keel-Kontsevich potentials. As a consequence\, we identified the two mirror constructions.
