Presentations for Generalized nilHecke Algebras
arXiv:1208.5260
Abstract
In this note presentations are given for the nilHecke algebras implicit in the work of Bressler and Evens on Schubert calculus for generalized cohomology theories. Such algebras do not usually satisfy the braid relation. Here the obstruction to the braid relation being satisfied is given explicitly and a connection with the deformation theory of algebras is made.
