Separation and Duality in Locally L0-Convex Modules

Motivated by financial applications, we study convex analysis for modules over the ordered ring L0 of random variables. We establish a module analogue of locally convex vector spaces, namely locally L0-convex modules. In this context, we prove hyperplane s ...

Utilisation des outils du système modulaire gradué (SMG) pour estimer les impacts des rejets pluviaux urbains: Avantages et limitations

David Andrew Barry, Luca Rossi, Kathrin Schneider

Today water bodies are suffering from numerous anthropogenic impacts. One of the key players is urban drainage. The directive STORM published by the VSA in 2007 proposes a procedure for an immission oriented strategy for remediation of urban drainage. At t ...

A geometry interface for gyrokinetic microturbulence investigations in toroidal configurations

Wilfred Anthony Cooper

The GENE/GIST code package is developed for the investigation of plasma microturbulence, suitable for both stellarator and tokamak configurations. The geometry module is able to process typical equilibrium files and create the interface for the gyrokinetic ...

Roombots-Mechanical Design of Self-Reconfiguring Modular Robots for Adaptive Furniture

Auke Ijspeert, Pierre Dillenbourg, Aude Billard

We aim at merging technologies from information technology, roomware, and robotics in order to design adaptive and intelligent furniture. This paper presents design principles for our modular robots, called Roombots, as future building blocks for furniture ...

Varieties of modules for Z/2Z x Z/2Z

Let k be an algebraically closed field of characteristic 2. We prove that the restricted nilpotent commuting variety C, that is the set of pairs of (n x n)-matrices (A, B) such that A(2) = B-2 = [A, B] = 0, is equidimensional. C can be identified with the ...

Mental vision: a computer graphics teaching platform

Daniel Thalmann, Frédéric Vexo, Achille Peternier

We have developed a learning platform to simplify and improve teaching and practice of computer graphics for beginners and advanced students. Our goal is to offer a set of tools to help students having a better mental vision of the abstract notions introdu ...

Groupes de Chow orientés

Jean Fasel

In this work we study the oriented Chow groups. These groups were defined by J. Barge et F. Morel in order to understand when a projective module P of top rank over a ring A has a free factor of rank one, i.e is isomorphic to Q ⊕ A. We show first that thes ...

The classification of torsion endo-trivial modules

Jacques Thévenaz

The main purpose of this paper is to show that, if G is a finite p-group which is not cyclic, quaternion or semi-dihedral, then the group of endo-trivial G-modules is detected on restriction to elementary abelian p-subgroups of rank 2. Consequently, the to ...
