WebSep 5, 2014 · Starting with Schur-Weyl duality, we explain how polynomials can be written down as symmetrizations of highest weight vectors in a tensor power of C^n. Studying these polynomials leads to interesting questions in combinatorics, for example a famous conjecture about Latin Squares by Alon and Tarsi. Our goal is to explain the results of … WebNov 4, 2024 · In two papers, Bürgisser and Ikenmeyer (STOC 2011, STOC 2013) used an adaption of the geometric complexity theory (GCT) approach by Mulmuley and Sohoni (Siam J Comput 2001, 2008) to prove lower bounds on the border rank of the matrix multiplication tensor. A key ingredient was information about certain Kronecker coefficients. While …
