%0 Journal Article %T Quadratic Forms and Inversive Geometry %A Nicholas Phat Nguyen %J Mathematics %D 2015 %I arXiv %X This paper develops an inversive geometry for anisotropic quadradic spaces, in analogy with the classical inversive geometry of a Euclidean plane. Such a generalization, although relatively straight-forward, does not seem to have been published or generally known, and therefore the account in this paper may be of interest and utility to some readers, especially as the theory has certain elegance. %U http://arxiv.org/abs/1509.05104v2
