The geometry of quasisymmetric coinvariants
Philippe Nadeau, Hunter Spink, Vasu Tewari
We develop a quasisymmetric analogue of the theory of Schubert cycles, building off of our previous work on a quasisymmetric analogue of Schubert polynomials and divided difference…
Schubert polynomial expansions revisited
Philippe Nadeau, Hunter Spink, Vasu Tewari
We give an elementary approach utilizing only the divided difference formalism for obtaining expansions of Schubert polynomials that are manifestly nonnegative, by studying solutio…
Quasisymmetric divided differences
Philippe Nadeau, Hunter Spink, Vasu Tewari
We develop a quasisymmetric analogue of the combinatorial theory of Schubert polynomials and the associated divided difference operators. Our counterparts are "forest polynomials",…
A Standard Rigid Transformation Notation Convention for Robotics Research
Philippe Nadeau
Notation conventions for rigid transformations are as diverse as they are fundamental to the field of robotics. A well-defined convention that is practical, consistent and unambigu…
Smirnov words and the Delta Conjectures
Alessandro Iraci, Philippe Nadeau, Anna Vanden Wyngaerd
We provide a combinatorial interpretation of the symmetric function in terms of segmented Smirnov words. The motivation for this…
