Log-uniruled affine varieties without cylinder-like open subsets

Adrien Dubouloz, Takashi Kishimoto

A classical result of Miyanishi-Sugie and Keel-McKernan asserts that for smooth affine surfaces, affine-uniruledness is equivalent to affine-ruledness, both properties being in fac…

$K (π, 1)$ conjecture for Artin groups

Luis Paris

The purpose of this paper is to put together a large amount of results on the $K (π, 1)$ conjecture for Artin groups, and to make them accessible to non-experts. Firstly, this is a s…

Pinczon Algebras

Didier Arnal

After recalling the construction of a graded Lie bracket on the space of cyclic multilinear forms on a vector space V, due to Georges Pinczon and Rosane Ushirobira, we prove this c…

The space of measured foliations of the hexagon

Athanase Papadopoulos, Guillaume Théret

The theory of geometric structures on a surface with nonempty boundary can be developed by using a decomposition of such a surface into hexagons, in the same way as the theory of g…

Persistent random walks, variable length Markov chains and piecewise deterministic Markov processes

Peggy Cénac, Brigitte Chauvin, Samuel Herrmann +1

A classical random walk $(S_{t}, t \in N)$ is defined by $S_{t} := n = 0 \sum t X_{n}$ , where $(X_{n})$ are i.i.d. When the increments $(X_{n})_{n \in N}$ are a one-…

Diamond module for the Lie algebra $so (2 n + 1, C)$

Boujemaa Agrebaoui, Didier Arnal, Abdelkader Ben Hassine

The diamond cone is a combinatorial description for a basis of an indecomposable module for the nilpotent factor $n$ of a semi simple Lie algebra. After N. J. Wildberger…
