摘要：
Presentations are given for the deformed nilHecke algebras which appear in the work of Bressler and Evens. The obstruction to the braid relation being satisfied by each algebra is given. A family of positively graded deformations of nilHecke algebras is defined and shown to be independent of the deformations determined by oriented cohomology theories. © 2014, Institute of Mathematics, Vietnam Academy of Science and Technology (VAST) and Springer Science+Business Media Singapore.
