SPHERE RefPlanets: Search for epsilon Eridani b and warm dust
C. Tschudi, H. M. Schmid, M. Nowak +35
We carried out very deep VLT/SPHERE imaging polarimetry of the nearby system Eps Eri based on 38.5 hours of integration time with a 600 - 900 nm broadband filter to search for pola…
Multipliers of a semigroup object in a monoidal category
Laurent Poinsot
The monoid of multipliers of a semigroup object in a monoidal category is introduced, arising from an abstraction of the definition of the translational hull of an ordinary semigro…
Hilbertian Frobenius algebras
Laurent Poinsot
Commutative Hilbertian Frobenius algebras are those commutative semi-group objects in the monoidal category of Hilbert spaces, for which the Hilbert adjoint of the multiplication s…
Stratification, segregation and mixing of granular materials in quasi-2D bounded heaps
Yi Fan, Youcef Boukerkour, Thibault Blanc +3
Segregation and mixing of granular mixtures during heap formation have important consequences in industry and agriculture. This research investigates three different final particle…
Optimisation of hybrid high-modulus/high-strength carbon fiber reinforced plastic composite drive
Olivier Montagnier, Christian Hochard
This study deals with the optimisation of hybrid composite drive shafts operating at subcritical or supercritical speeds, using a genetic algorithm. A formulation for the flexural…
C-simple groups: amalgamated free products, HNN extensions, and fundamental groups of 3-manifolds
Pierre de la Harpe, Jean-Philippe Préaux
We establish sufficient conditions for the C-simplicity of two classes of groups. The first class is that of groups acting on trees, such as amalgamated free products, HNN-exte…
