Web1 de abr. de 1993 · It is also known (cf. [4] or [3], for example) that the kernel of the representations of the form (n - k, k) contain the Burau kernel so that ~ lies in the kernel of these representations as well. One can also verify nontriviality directly as the closure has a 3-component nontrivial sublink coming from the first three strands; this is easily checked … WebDOI: 10.5539/JMR.V8N1P5 Corpus ID: 55319379; Attacks on the Faithfulness of the Burau Representation of the Braid Group $B_4$ @article{Chreif2016AttacksOT, title ...
