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 ... WebBurau. Methods for finding kernel elements of the B_4 Burau representation, or helping to show that no non-trivial elements of the kernel exist.. Background. Here, we follow the lead from Bigelow and consider a particular family of pairs of curves in the four-punctured disc. We follow more or less the same prescription as in Bigelow's C implementation currently …
