In this article we construct a piecewise Euclidean, non-positively curved 2
-complex for the 3-generator Artin groups of large type. As a consequence w
e show that these groups are biautomatic. A slight modification of the proo
f shows that many other Artin groups are also biautomatic. The general ques
tion (whether all Artin groups are biautomatic) remains open. (C) 2000 Else
