While objects like spheres and cones have allowed us to create elegant geometry from a small number of simple commands, we clearly need more flexible surfaces that will allow us to model a wider range of shapes. In this chapter we will introduce a number of surface types that allow you to create almost any form of object.

Maps Between Complex Hyperbolic Surfaces
Geometriae Dedicata, 2003The author studies examples of holomorphic mappings between complex hyperbolic surfaces that are not covering mappings. We note that, in this paper, a complex hyperbolic surface means a compact quotient of the unit ball in \(\mathbb{C}^2\). Those mappings induce homomorphisms on the fundamental groups that have infinite kernel.

Im reellen projektiven Raum \(P^ 3\) sei S eine auf Schmiegparameter u,v bezogene Fläche mit dem Projektivbogenelement \((\beta du^ 3+\gamma dv^ 3)/(2 du dv)\). Die Tangenten der Kurvenschar B du-A dv\(=0\) in S mit \(A\neq 0\), \(B\neq 0\), \(A_ v+\gamma B=B_ u+\beta A=0\) bilden eine W- Kongruenz (A,B), bei deren Ableitungsgleichungen weitere ...

Surface Complexation at (Hydr)Oxide Surfaces
1991This chapter is concerned with some aspects of the interaction of oxide/hydroxide surfaces with electrolyte solutions. It specially covers interactions with hydrogen- and hydroxide ions, with metal ions (Lewis to the (hydr)oxide-water interface. It leads to an accumulation of matter at the interface without the development of a three dimensional ...

Developed over more than a century, and still an active area of research today, the classification of algebraic surfaces is an intricate and fascinating branch of mathematics. In this book Professor Beauville gives a lucid and concise account of the subject, following the strategy of F.

Complex Surfaces and Coverings
2017This chapter deals with complex surfaces and their finite coverings branched along divisors, that is, subvarieties of codimension 1. In particular, it considers coverings branched over transversally intersecting divisors. Applying this to linear arrangements in the complex projective plane, the chapter first blows up the projective plane at non ...
