Title: Relating Edelman-Greene insertion and the Little map
Abstract: The study of reduced decompositions of symmetric group elements has been a rich source for combinatorial problems since being introduced by Stanley in 1980. Shortly after, major breakthroughs were made via an RSK-like insertion algorithm developed by Edelman and Greene and algebraic results of Lascoux and Schutzenberger. In 2000 David Little demonstrated a bijective realization of Lascoux and Schutzenberger's results. We relate Edelman-Greene insertion to the Little map, tying together this body of work and proving new properties about each map. This is joint work with Benjamin Young.
