Abstract
AbstractWe describe reduced representatives for positive Rouquier complexes. These are obtained via Morse theoretical Gaussian elimination from the corresponding standard representatives. The underlying graded object is still a direct sum of Bott–Samelson objects, but over subwords rather than subexpressions.
