Algebraic ellipticity of quartic double spaces
Alexander Dvorsky, Shulim Kaliman, Mikhail Zaidenberg
We prove that every smooth quartic double -fold, , over an algebraically closed field of characteristic zero is algebraically elliptic in Gromov's sense. In particular, e…
Tame Discrete Sets on Affine Semisimple Homogeneous Spaces
Alexander Dvorsky
Winkelmann conjectures that every smooth flexible complex affine variety of dimension at least two is a Rosay--Rudin space. We verify this for every positive-dimensional quotient $…
The Unfair 0-1 Polynomial Problem and High-Degree Trinomials
Alexander Dvorsky
The unfair -- polynomial conjecture asks whether a factorization \[C(x)=A(x)B(x),\] with and monic and having nonnegative real coefficients, and a polynomial with…
An Explicit Five-Variable Counterexample to the Generalized Vanishing Conjecture
Alexander Dvorsky
We give an explicit counterexample in five variables to the Generalized Vanishing Conjecture. The construction is motivated by the recent counterexample to the Mathieu conjecture f…
Algebraic density property of homogeneous spaces
Fabrizio Donzelli, Alexander Dvorsky, Shulim Kaliman
Let be an affine algebraic variety with a transitive action of the algebraic automorphism group. Suppose that is equipped with several non-degenerate fixed point free $SL_2…
Explicit Hilbert spaces for certain unipotent representations III
Alexander Dvorsky, Siddhartha Sahi
We consider the groups G which arise from real semisimple Jordan algebras via the Tits-Koecher-Kantor construction. Such a G is characterized by the fact that it admits a parabolic…
