Topology of Real Aronhold Systems in \(\mathbb {P}^2\)
摘要
In this paper we outline and develop further results obtained in (Finashin and Zabun Topol. Its Appl. 194, 358–385 (2015)) They concern real deformation classification of so called typical 7-configurations, which is equivalent to the real deformation classification of the Aronhold systems of bitangents to a maximal real quartic. In turn we justify that a quartic is determined by a 7-arrangement of lines forming an Aronhold system.
