DESCRIPTION:Title: <a href="https://researchseminars.org/talk/agstanford/1
 41/">A new divided difference\, with applications to Schubert polynomials<
 /a>\nby Hunter Spink (University of Toronto) as part of Stanford algebraic
  geometry seminar\n\nLecture held in 380-W (unusual room!).\n\nAbstract\nI
  will talk about a new algebra of operations on polynomials which has the 
 property \n$T_iT_j=T_jT_{i+1}$ for $i>j$ and a family of polynomials dual 
 to them called forest polynomials. This family of operations plays the exa
 ct role for quasisymmetric polynomials and forest polynomials as the divid
 ed difference operations play for symmetric polynomials and Schubert polyn
 omials. (Joint with Philippe Nadeau and Vasu Tewari)\n
