Ivan DYNNIKOV (MSU, Moscow): On the complexity of braids . We define a measure of "complexity" of a braid which is natural with respect to both an algebraic and a geometric point of view. ... The geometrical complexity is some natural measure of the amount of distortion of the $n$ times punctured disk caused by a homeomorphism. Our main result is that the two notions of complexity are comparable. ...
