%0 Journal Article %T Hofer's metric on the space of diameters %A M. Khanevsky %J Mathematics %D 2009 %I arXiv %X The present paper considers Hofer's distance between diameters in the unit disk. We prove that this distance is unbounded and show its relation to Lagrangian intersections. %U http://arxiv.org/abs/0907.1499v1
