SUMMARY:Workshop / Seminar:Monomial identities in the Weyl algebra (Combinatorics Seminar)
DESCRIPTION:The (Heisenberg) Weyl algebra is the free algebra with two generators D and U and single relation DU−UD = 1.  As a consequence of this relation\, certain monomials are equal\, such as DUUD and UDDU. We characterize all such equalities over a field of characteristic 0\, describing them in several ways\, including operationally (by a combinatorial  equivalence relation generated by certain moves) and computationally (through lattice path invariants).  We also enumerate the equivalence classes and several variants thereof and discuss possible extensions to other algebras.
