16, 6 Configurations And Geometry Of Kummer Surfaces In P3 (memoirs Of The American Mathematical Society)

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.

In addition, the beautiful connections to the theory of K3 surfaces and abelian varieties are studied. The philosophy of the first part of this work is to understand (and classify) Kummer surfaces by studying (16, 6) configurations. Chapter 1 is devoted to classifying (16, 6) configurations and studying their manifold symmetries and the underlying questions about finite subgroups of [italic capitals]PGL4([italic]k). In chapter 2 we use this information to give a complete classification of Kummer surfaces together with explicit equations and the explicit description of their singularities
