# \((16,6)\) Configurations and Geometry of Kummer Surfaces in \(\mathbb P^{3}\)

Share this page
*Maria R. Gonzalez-Dorrego*

This monograph studies the geometry of a Kummer surface in \({\mathbb P}^3_k\) and of its minimal desingularization, which is a K3 surface (here \(k\) is an algebraically closed field of characteristic different from 2). This Kummer surface is a quartic surface with sixteen nodes as its only singularities. These nodes give rise to a configuration of sixteen points and sixteen planes in \({\mathbb P}^3\) such that each plane contains exactly six points and each point belongs to exactly six planes (this is called a “(16,6) configuration”). A Kummer surface is uniquely determined by its set of nodes. Gonzalez-Dorrego classifies (16,6) configurations and studies their manifold symmetries and the underlying questions about finite subgroups of \(PGL_4(k)\). She uses this information to give a complete classification of Kummer surfaces with explicit equations and explicit descriptions of their singularities. In addition, the beautiful connections to the theory of K3 surfaces and abelian varieties are studied.
