Approximation of the two-dimensional Dirichlet problem by one-dimensional continuous and discrete problems on one-dimensional networks

Maryse Bourlard-Jospin, Serge Nicaise, Juliette Venel

We show that the solution of the two-dimensional Dirichlet problem set in a plane domain is the limit of the solutions of similar problems set on a sequence of one-dimensional networks as their size goes to zero. Roughly speaking this means that a membrane can be seen as the limit of rackets made...

Linear Multifractional Stable Motion: fine path properties

Antoine Ayache, Julien Hamonier

Linear Multifractional Stable Motion (LMSM), denoted by $\{Y(t):t\in\R\}$, has been introduced by Stoev and Taqqu in 2004-2005, by substituting to the constant Hurst parameter of a classical Linear Fractional Stable Motion (LFSM), a deterministic function $H(\cdot)$ depending on the time variable $...

Classes de Steinitz dʼextensions galoisiennes à groupe de Galois de centre non trivial

Bouchaïb Sodaïgui

Let k be a number field and Cl(k) its class group. Let Γ be a finite group and |Γ| its order. Let R(k, Γ) (resp. R m(k, Γ)) be the subset of Cl(k) consisting of those classes which are realizable as Steinitz classes of Galois extensions (resp. tamely ramified Galois extensions) of k with Galois...

On Some Holomorphic Cohomological Equations

Aziz El Kacimi Alaoui

Let Σ be a non compact Riemann surface and γ:Σ⟶Σ an automorphism acting freely and properly such that the quotient M = Σ/γ is a non compact Riemann surface. Using the fact that Σ and M are Stein manifolds, we prove that, for any holomorphic function g:Σ⟶C and any λ∈C , there exists a holomorphic...

Animation réaliste d’une caméra pour la stop motion : de la modélisation à la prise de vue

Laura Saini, Gudrun Albrecht, Nicolas Lissarrague, Lucia Romani

L’article présente un nouveau système permettant de produire des mouvements de caméra réalistes pour l’animation stop motion. Le système permettra d’enrichir les logiciels d’animation 3D classiques (comme par exemple Maya et 3D Studio Max) afin de leur faire contrôler des mouvements de caméra pour..., The article presents a new system that allows to create realistic camera movements for a stop motion animation. The system improves traditional 3D software animation programs (for example Maya and 3D Studio Max) for creating stop motion camera movements by using a haptic interface. After describing...

Numerical approximation for options pricing of a stochastic volatility jump-diffusion model

Rajae Aboulaich, Fouzia Baghery, Abdelilah Jraifi

In this paper, we are interested in pricing options (European and Quanto) by a Model in which the asset prices follow a jump-diffusion model with a stochastic volatility in n dimensions. The stochastic volatility also follows the jump-diffusion in d dimensions. We've already stated the...

Calcite as a bone substitute. Comparison with hydroxyapatite and tricalcium phosphate with regard to the osteoblastic activity

Francine Monchau, Philippe Hivart, Benoit Genestie, Feng Chai, Michel Descamps, Hartmut Frederic Hildebrand

Close to the bone mineral phase, the calcic bioceramics, such as hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP), are commonly used as substitutes or filling materials in bone surgery. Besides, calcium carbonate (CaCO3) is also used for their excellent biocompatibility and bioactivity....
