On the burau representation of b 4

Webends of some braid b. The Alexander polynomial A(K) was defined in terms of a certain matrix A of relations. In 1-926, Alexander found that A(K) does not uniquely determine the knot K [1]. Subsequently, Burau wrote down, for each braid b, a matrix of Alexander relations of the form A(b) - 1 for the associated knot or link, such that the 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 ...

WebSubsequently, Burau wrote down, for each braid b, a matrix of Alexander relations of the form A(b) - 1 for the associated knot or link, such that the matrix of a composite bb' satisfies A(bb') = A(b)A(b'). For generic values of the variable, Burau's representation (modulo a line) is Zariski dense, so its exterior powers are distinct irreducible ...
