S ep 2 00 8 SMOOTH AFFINE SURFACES WITH NON - UNIQUE C ∗ - ACTIONS
In this paper we complete the classification of effective C-actions on smooth affine surfaces up to conjugation in the full automorphism group and up to inversion λ 7→ λ of C. If a smooth affine surface V admits more than one C-action then it is known to be Gizatullin i.e., it can be completed by a linear chain of smooth rational curves. In [FKZ3] we gave a sufficient condition, in terms of the...
متن کاملNon - singular affine surfaces with self - maps
We classify surjective self-maps (of degree at least two) of affine surfaces according to the log Kodaira dimension. In this paper we are interested in the following question. Question. Classify all smooth affine surfaces X/C which admit a proper morphism f : X → X with degree f > 1. In [5] and [18], a classification of smooth projective surfaces with a self-map of degree > 1 has been given. Th...
متن کاملSmooth surfaces from bilinear patches: Discrete affine minimal surfaces☆
Motivated by applications in freeform architecture, we study surfaces which are composed of smoothly joined bilinear patches. These surfaces turn out to be discrete versions of negatively curved affine minimal surfaces and share many properties with their classical smooth counterparts. We present computational design approaches and study special cases which should be interesting for the archite...
متن کاملSmooth Surfaces with Non-simply-connected Complements
We give two constructions of surfaces in simply-connected 4-manifolds with non simply-connected complements. One is an iteration of the twisted rim surgery introduced by the first author [7]. We also construct, for any group G satisfying some simple conditions, a simply-connected symplectic manifold containing a symplectic surface whose complement has fundamental group G. In each case, we produ...
متن کاملAcyclic curves and group actions on affine toric surfaces
We show that every irreducible, simply connected curve on a toric affine surface X over C is an orbit closure of a Gm-action on X . It follows that up to the action of the automorphism group Aut(X) there are only finitely many non-equivalent embeddings of the affine line A in X . A similar description is given for simply connected curves in the quotients of the affine plane by small finite line...
