Thurston's metric on Teichmüller space and isomorphisms between Fuchsian groups
Athanase Papadopoulos, Weixu Su
The aim of this paper is to relate Thurston's metric on Teichmüller space to several ideas initiated by T. Sorvali on isomorphisms between Fuchsian groups. In particular, this will…
Continuity and finiteness of the radius of convergence of a p-adic differential equation via potential theory
Jérôme Poineau, Andrea Pulita
We study the radius of convergence of a differential equation on a smooth Berkovich curve over a non-archimedean complete valued field of characteristic 0. Several properties of th…
A Remark on the Projective Geometry of Constant Curvature Spaces
Athanase Papadopoulos, Sumio Yamada
We highlight the relation between the projective geometries of -dimensional Euclidean, spherical and hyperbolic spaces through the projective models of these spaces in the …
Polynomial functors from Algebras over a set-operad and non-linear Mackey functors
Manfred Hartl, Teimuraz Pirashvili, Christine Vespa
In this paper, we give a description of polynomial functors from (finitely generated free) groups to abelian groups in terms of non-linear Mackey functors generalizing those given…
Constraints on counterexamples to the Casas-Alvero conjecture, and a verification in degree 12
Wouter Castryck, Robert Laterveer, Myriam Ounaïes
In a first (theoretical) part of this paper, we prove a number of constraints on hypothetical counterexamples to the Casas-Alvero conjecture, building on ideas of Graf von Bothmer,…
Finite subgroups of extended Morava stabilizer groups
Cedric Bujard
The problem addressed is the classification up to conjugation of the finite subgroups of the (classical) Morava stabilizer group S_n and the extended Morava stabilizer group G_n(u)…
