Cohomology of Coxeter arrangements and Solomon's descent algebra
(American Mathematical Society, 2014-06-19)We refine a conjecture by Lehrer and Solomon on the structure of the Orlik-Solomon algebra of a finite Coxeter group W and relate it to the descent algebra of W. As a result, we claim that both the group algebra of W and ... -
Computations for Coxeter arrangements and Solomon's descent algebra III: Groups of rank seven and eight
(Elsevier, 2014-11-06)In this paper we extend the computations in parts I and II of this series of papers and complete the proof of a conjecture of Lehrer and Solomon expressing the character of a finite Coxeter group W acting on the p-th graded ... -
Maths was fine until they brought the alphabet into it: An examination of Irish 14-year-olds' knowledge of initial algebra
(NUI Galway, 2021-02-26)The aim of this research is to establish what second-year students (age approximately 14 years) in Ireland know about initial algebra. To measure this knowledge, a standardised criterion referenced screener has been ...
