Braid groups are linear. (English) Zbl 0988.20021
{\it D. Krammer} [Invent. Math. 142, No. 3, 451-486 (2000; see the review Zbl 0988.20023 below)] proved that a representation of the braid groups $B_n$ is faithful in the case $n=4$. The representation Krammer used is essentially the same as one used by {\it R. J. Lawrence} [Commun. Math. Phys. 135, No. 1, 141-191 (1990; Zbl 0716.20022)]. The author calls this representation the Lawrence-Krammer representation. In the paper the author proves by topological methods that the Lawrence-Krammer representation is faithful for all $n$.
