Algorithm for Lang's Theorem
Arjeh M. Cohen, Scott H. Murray
We give an efficient algorithm for Lang's Theorem in split connected reductive groups defined over finite fields of characteristic greater than 3. This algorithm can be used to con…

On a theorem of Artin
Arjeh M. Cohen, Luis Paris
We determine the epimorphisms from the Artin group of type onto the Coxeter group of type , in case is an irreducible Coxeter graph of spherical type,…

Linearity of Artin groups of finite type
Arjeh M. Cohen, David B. Wales
Recent results on the linearity of braid groups are extended in two ways. We generalize the Lawrence Krammer representation as well as Krammer's faithfulness proof for this linear…
