%0 Journal Article %T An Introduction to Inversion in an Ellipse %A Jos¨¦ L. Ram¨ªrez %J Mathematics %D 2013 %I arXiv %X In this paper we study the inversion in an ellipse and some properties, which generalizes the classical inversion with respect to a circle. We also study the inversion in an ellipse of lines, ellipses and other curves. Finally, we generalize the Pappus Chain with respect to ellipses and the Pappus Chain Theorem. %U http://arxiv.org/abs/1309.6378v1
