WebIn mathematics the Burau representation is a representation of the braid groups, named after and originally studied by the German mathematician Werner Burau [1] during the … 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 …
