 ">Quantum Schubert Calculus from lattice models</a>\nby Leonardo Mihalcea 
 (Virginia Tech) as part of MAAGC 2026\n\nLecture held in Temple 1169.\n\nA
 bstract\nQuantum Schubert Calculus arises from questions in Enumerative Ge
 ometry\, such as how many rational curves of a specified degree intersect 
 general translates of Schubert varieties in a Grassmannian. The answer may
  be found by calculating the structure constants of the multiplication of 
 Schubert classes in an appropriate quantum intersection ring associated to
  a Grassmann manifold. I will explain how techniques from statistical mech
 anics\, namely the combinatorics of partition functions of certain lattice
  models\, yield explicit combinatorial formulae for the Schubert structure
  constants. Joint work with V. Gorbounov and C. Korff.\n
