+ | We use the spectrum of the Burau representation to introduce | ||
+ | a series of tests for a braid being conjugate | ||
+ | to a reducible braid, valid for every braid group. | ||
+ | The method can be extended to exchangeable and | ||
+ | composite braids and to Markov equivalence. | ||
+ | We also determine the exact location of | ||
+ | the eigenvalues of the Burau matrix (for suitable | ||
+ | parameter), with those | ||
+ | for reducible braids filling a complex disk and | ||
+ | for the exchange move a Descartes oval. | ||
