  • On the complexity of multiplication in the Iwahori-Hecke algebra of the symmetric group 

    Niemeyer, Alice C.; Pfeiffer, Götz; Praeger, Cheryl E. (Elsevier, 2016-09-12)
    We present new efficient data structures for elements of Coxeter groups of type Am and their associated Iwahori Hecke algebras H(A(m)). Usually, elements of H(A(m)) are represented as simple coefficient list of length M = ...
  • A quiver presentation for Solomon's descent algebra 

    Pfeiffer, Götz (Elsvier, 2009)
    The descent algebra S(W) is a subalgebra of the group algebra of a finite Coxeter group W, which supports a homomorphism with nilpotent kernel and commutative image in the character ring of W. Thus S(W) is a basic algebra, ...
