Eveliina Peltola - On variants of Specht polynomials and random geometry - IPAM at UCLA

Recorded 28 March 2024. Eveliina Peltola of Aalto University presents "On variants of Specht polynomials and random geometry" at IPAM's Statistical Mechanics and Discrete Geometry Workshop. Abstract: Certain classes of polynomials associated with column-strict, rectangular Young tableaux, that we call (fused) Specht polynomials, give explicit formulas for conformal blocks (partition functions) describing a general class of conformally invariant boundary conditions and crossing probabilities for models building on the Gaussian free field (GFF): e.g. double-dimers contours and multi-dimer webs of higher degree. Also, analogous determinantal formulas describe the geometry of uniform spanning tree (UST) branches (loop-erased walks). These objects also display rich algebraic content: they carry irreducible representations of certain diagram algebras: e.g., the (fused) Hecke algebra, Temperley-Lieb algebra, or the Kuperberg algebra defined from sln webs. I shall discuss the general framework and results towards the connection to random geometry. While the precise connection is partly conjectural, it has been verified in special cases.
