Dual Equivalence Graphs Revisited and the Explicit Schur Expansion of a Family of LLT Polynomials
In 2007 Sami Assaf introduced dual equivalence graphs as a method for demonstrating that a quasisymmetric function is Schur positive. The method involves the creation of a graph whose vertices are weighted by Ira Gessel's fundamental quasisymmetric functions so that the sum of the weights of a...
