%0 Journal Article %T Semi-continuity of Siegel disks under parabolic implosion %A Arnaud Cheritat %J Mathematics %D 2005 %I arXiv %X We transfer the lower semi-continuity of Siegel disks with fixed Brjuno type rotation numbers to geometric limits. Here, we restrict to Lavaurs maps associated to quadratic polynomials with a parabolic fixed point. %U http://arxiv.org/abs/math/0507250v1
