报告摘要：

We prove Lusztig's conjectures P1-P15 for Coxeter groups with complete graph, using deceasing induction on a-values and a kind of decomposition formula of Kazhdan-Lusztig basis elements. As a byproduct, we can give a description of the left, right, and two-sided cells. These methods also work for right-angled Coxeter groups and hyperbolic Coxeter groups of rank 3.
