Bifurcations in the elementary Desboves family

2017

International audience; We give an example of a family of endomorphisms of $\mathbb{P}^2(\mathbb{C})$ whose Julia set depends continuously on the parameter and whose bifurcation locus has non-empty interior.

Categorical action of the extended braid group of affine type $A$

2017

Using a quiver algebra of a cyclic quiver, we construct a faithful categorical action of the extended braid group of affine type A on its bounded homotopy category of finitely generated projective modules. The algebra is trigraded and we identify the trigraded dimensions of the space of morphisms of this category with intersection numbers coming from the topological origin of the group.

Hom-Lie quadratic and Pinczon Algebras

2017

ABSTRACTPresenting the structure equation of a hom-Lie algebra 𝔤, as the vanishing of the self commutator of a coderivation of some associative comultiplication, we define up to homotopy hom-Lie algebras, which yields the general hom-Lie algebra cohomology with value in a module. If the hom-Lie algebra is quadratic, using the Pinczon bracket on skew symmetric multilinear forms on 𝔤, we express this theory in the space of forms. If the hom-Lie algebra is symmetric, it is possible to associate to each module a quadratic hom-Lie algebra and describe the cohomology with value in the module.

Unfolding of saddle-nodes and their Dulac time

2016

Altres ajuts: UNAB10-4E-378, co-funded by ERDF "A way to build Europe" and by the French ANR-11-BS01-0009 STAAVF. In this paper we study unfoldings of saddle-nodes and their Dulac time. By unfolding a saddle-node, saddles and nodes appear. In the first result (Theorem A) we give a uniform asymptotic expansion of the trajectories arriving at the node. Uniformity is with respect to all parameters including the unfolding parameter bringing the node to a saddle-node and a parameter belonging to a space of functions. In the second part, we apply this first result for proving a regularity result (Theorem B) on the Dulac time (time of Dulac map) of an unfolding of a saddle-node. This result is a b…

Free vs. Locally Free Kleinian Groups

2015

Abstract We prove that Kleinian groups whose limit sets are Cantor sets of Hausdorff dimension < < 1 are free. On the other hand we construct for any ε > > 0 an example of a non-free purely hyperbolic Kleinian group whose limit set is a Cantor set of Hausdorff dimension < < 1 + + ε.

Characterization of the Clarke regularity of subanalytic sets

2017

International audience; In this note, we will show that for a closed subanalytic subset $A \subset \mathbb{R}^n$, the Clarke tangential regularity of $A$ at $x_0 \in A$ is equivalent to the coincidence of the Clarke's tangent cone to $A$ at $x_0$ with the set \\$$\mathcal{L}(A, x_0):= \bigg\{\dot{c}_+(0) \in \mathbb{R}^n: \, c:[0,1]\longrightarrow A\;\;\mbox{\it is Lipschitz}, \, c(0)=x_0\bigg\}.$$Where $\dot{c}_+(0)$ denotes the right-strict derivative of $c$ at $0$. The results obtained are used to show that the Clarke regularity of the epigraph of a function may be characterized by a new formula of the Clarke subdifferential of that function.

Le rôle déterminant de la presse dans la vie des expulsés allemands

2016

This article focuses on the identity of the German expellees after World War II through the study of one of their publications, the Grafschafter Bote. For this population who is spread geographically all over Germany, the newspapers published by numerous associations have contributed to the creation and the maintaining of a collective identity able to sustain its position in the new German state. These newspapers still exist today and contribute to the strengthening of a particular identity.

Le mélodrame ou le rapt de l’Histoire. El secreto de sus ojos (Juan José Campanella, 2009)

2017

This text offers to analyse Juan José Campanella’s picture El secreto de sus ojos (2009) connecting it with its coherence or distance in respect to traditional codes of melodrama. The male and sometimes ironic focus on pathetic possibilities seems to present it as an inverted melodrama. The love story seems to be pushed into the background by the investigation of a criminal case in pre-dictatorial context, whereas in actual fact, the three levels of the synopsis intertwine to build the framework’s logic. Regarding the Hollywood remake of the picture will allow us to evaluate the relationship of each one with the national imaginative world, History and the concept of justice. Through this re…

Héros et criminels : la figure du peuple en lutte dans les débats d’amnistie de la question sociale sous la Troisième République

2014

Sous la Troisieme Republique, l’amnistie est classiquement utilisee pour regler les grandes crises civiles (boulangisme, affaire Dreyfus), mais elle devient de maniere plus nouvelle un outil de regulation du conflit social a une epoque ou les greves se multiplient, le monde du travail se transforme et la repression sociale s’intensifie. Pour des raisons pedagogiques liees a la naissance du syndicalisme et a l’organisation du socialisme, les campagnes d’amnistie, de plus en plus personnalisees, produisent, au risque de simplifier a l’extreme les enjeux de la lutte sociale, des heros et des martyrs, alors que les defenseurs de l’ordre denoncent, dans la tradition renouvelee des « classes dang…
