Some properties of dynamical degrees with a view towards cubic fourfolds
Christian Böhning, Hans-Christian Graf von Bothmer, Pawel Sosna
Dynamical degrees and spectra can serve to distinguish birational automorphism groups of varieties in quantitative, as opposed to only qualitative, ways. We introduce and discuss s…
Birationally isotrivial fiber spaces
Fedor Bogomolov, Christian Böhning, Hans-Christian Graf von Bothmer
We prove that a family of varieties is birationally isotrivial if all the fibers are birational to each other.
Algorithmic construction of Hurwitz maps
Laurent Bartholdi, Xavier Buff, Hans-Christian Graf von Bothmer +1
We describe an algorithm that, given a k-tuple of permutations representing the monodromy of a rational map, constructs an arbitrarily precise floating-point complex approximation…
Rationality of quotients by linear actions of affine groups
Fedor Bogomolov, Christian Böhning, Hans-Christian Graf von Bothmer
Let G be the (special) affine group, semidirect product of SL_n and C^n. In this paper we study the representation theory of G and in particular the question of rationality for V/G…
Linear precision for toric surface patches
Hans-Christian Graf von Bothmer, Kristian Ranestad, Frank Sottile
We classify the homogeneous polynomials in three variables whose toric polar linear system defines a Cremona transformation. This classification also includes, as a proper subset,…
