The geometry of sporadic -embeddings into
Mariusz Koras, Karol Palka, Peter Russell
A closed algebraic embedding of into is 'sporadic' if for every curve isomorphic to an affine lin…
Families of Group Actions, Generic Isotriviality, and Linearization
Hanspeter Kraft, Peter Russell
We prove a "Generic Equivalence Theorem which says that two affine morphisms and of varieties with isomorphic (closed) fibers become isomorphic under a do…
Some properties of C* in C^2
Mariusz Koras, Peter Russell
We consider plane curves isomorphic to C*. We prove that with one exception the branches at infinity can be separated by an automorphism of C^2. We also give a bound for selfinters…
A homology plane of general type can have at most a cyclic quotient singularity
R. V. Gurjar, M. Koras, M. Miyanishi +1
We show that a homology plane of general type has at worst a single cyclic quotient singular point. An example of such a surface with a singular point does exist. We also show that…
Open problems on open algebraic varieties
R. V. Gurjar, Shulim Kaliman, N. Mohan Kumar +5
This report records a large number of open problems in Affine Algebraic Geometry that were proposed by participants in a Conference on Open Algebraic Varieties at the Centre de Rec…
