We classify webs of minimal degree rational curves on surfaces and give a criterion for webs being hexagonal. In addition, we classify Neron–Severi lattices of real weak del Pezzo surfaces. These two classifications are related to root subsystems of E8.

Surfaces that are covered by two pencils of circles

We list up to M\"obius equivalence all possible degrees and embedding dimensions of real surfaces that are covered by at least two pencils of circles, together with the number of such pencils. In



Explicit Real Cubic Surfaces

Abstract The topological classification of smooth real cubic surfaces is recalled and compared to the classification in terms of the number of real lines and of real tritangent planes, as obtained by

Minimal degree rational curves on real surfaces

Computing curves on real rational surfaces

This work presents an algorithm for computing curves and families of curves of prescribed degree and geometric genus on real rational surfaces and shows how this algorithm can be modified for curved topographies.

Real Algebraic Surfaces

These are the notes for my lectures at the Trento summer school held September 1997. The aim of the lectures is to provide an introduction to real algebraic surfaces using the minimal model program.

Real Algebraic Surfaces

Results on real algebraic surfaces show linear cycles on real varieties and application to rational surfaces are similar to that on real abelian varieties.

The Multiple Conical Surfaces

We give a classification of the surfaces that can be generated by a moving conic in more than one way. It turns out that these surfaces belong to classes which have been thoroughly studied in other


In this paper, we consider the classification of singularities [P. Du Val, On isolated singularities of surfaces which do not affect the conditions of adjunction. I, II, III, Proc. Camb. Philos.

3-Webs generated by confocal conics and circles

We consider families of confocal conics and two pencils of Apollonian circles having the same foci. We will show that these families of curves generate trivial 3-webs and find the exact formulas

Classification of regular three-webs formed by pencils of circles

We prove that there exist no regular three-webs except for those listed by V. Lazareva.

Real forms of smooth del Pezzo surfaces.

Work on real forms is also classical: for cubic surfaces, beginning with Schl fli [13]; for quartic curves the best reference is Zeuthen [21] (see also [5]); while for a surface of intersection of
