The classification of surfaces with p_g = q = 0 isogenous to a product of curves
Ingrid Bauer, Fabrizio Catanese, Fritz Grunewald
We classify all the surfaces with p_g = q = 0 which admit an unramified covering which is isomorphic to a product of curves. Beyond the trivial case \PP^1 x \PP^1 we find 17 famili…
A commutator description of the solvable radical of a finite group
Nikolai Gordeev, Fritz Grunewald, Boris Kunyavskii +1
We are looking for the smallest integer k>1 providing the following characterization of the solvable radical R(G) of any finite group G: R(G) coincides with the collection of all g…
Linear Representations of the Automorphism Group of a Free Group
Fritz Grunewald, Alexander Lubotzky
Let be the free group on elements and $\A(F_n)$ its group of automorphisms. In this paper we present a rich collection of linear representations of $\A(F_n)$ arising…
Chebycheff and Belyi polynomials, dessins d'enfants, Beauville surfaces and group theory
Ingrid Bauer, Fabrizio Catanese, Fritz Grunewald
We start discussing the group of automorphisms of the field of complex numbers, and describe, in the special case of polynomials with only two critical values, Grothendieck's progr…
