The kernel of $B u r a u (4) \otimes Z_{p}$ is all pseudo-Anosov

Sang Jin Lee, Won Taek Song

We show that the kernel of $B u r a u (4) \otimes Z_{p}$ , the reduced Burau representation with coefficients in $Z_{p}$ of the 4-braid group $B_{4}$ , consists only of pseudo-Anosov braids.

The infimum, supremum and geodesic length of a braid conjugacy class

Joan S. Birman, Ki Hyoung Ko, Sang Jin Lee

Algorithmic solutions to the conjugacy problem in the braid groups B_n were given by Elrifai-Morton in 1994 and by the authors in 1998. Both solutions yield two conjugacy class inv…
