Minimal genus of Seifert surface of torus knot - MathOverflow
WebBy definition the canonical genus of a knot K gives an upper bound for the genus g(K) of K, that is the minimum of genera of all possible Seifert surfaces for K. In this paper, we introduce an operation, called the bridge-replacing move, for a knot diagram which does not change its representing knot type and does not increase the genus of the ...

Help Contact Us Web13 de fev. de 2015 · The degree of the Alexander polynomial gives a bound on the genus, so we get 2 g ( T p, q) ≥ deg Δ T p, q = ( p − 1) ( q − 1). Since this lower bound agrees with the upper bound given by Seifert's algorithm, you're done. Here's another route: the standard picture of the torus knot is a positive braid, so applying Seifert's algorithm ... http://people.mpim-bonn.mpg.de/stavros/publications/mutation.pdf griffe de terreur wow classic
