Efficient algorithms in Coxeter groups of large type

Abstract

dc:description

We establish a quadratic time algorithm for the word problem and a cubic time algorithm for the conjugacy problem for Coxeter groups of large type. We also give conditions on the relators of a large-type Coxeter group that are necessary and sufficient for the group to be hyperbolic, and we give a normal form for large-type Coxeter groups that is a regular bicombing, thus establishing that all such groups are biautomatic.
