%0 Journal Article %T Partial symmetry, reflection monoids and Coxeter groups %A Brent Everitt %A John Fountain %J Mathematics %D 2008 %I arXiv %X This is the first of a series of papers in which we initiate and develop the theory of reflection monoids, motivated by the theory of reflection groups. The main results identify a number of important inverse semigroups as reflection monoids, introduce new examples, and determine their orders. %U http://arxiv.org/abs/0812.2789v2
