A New Descent Algebra for Weyl Groups of Type An
A New Descent Algebra for Weyl Groups of Type An
摘要
In this paper we define an equivalence relation on the set of all xj in order to form a basis for a new descent algebra of Weyl groups of type A,. By means of this, we construct a new commutative and semi-simple descent algebra for Weyl groups of type An generated by equivalence classes arising from this equivalence relation.
