Grupos de nudos con dos generadores

abstract.we study knot groups that admit a presentation with two generators and one relation. we say that a presentation is palindromic if r is a palindrome, that is, if r is a word that reads the same forwards and backwards. we study conditions that allow us to change the given presentation to obtain a palindromic presentation. we prove that if the knot group g admits a faithful discrete sl(2,？)-representation then g admits a palindromic presentation.
