The 2d-directed spanning forest converges to the Brownian web

David Coupier, Kumarjit Saha, Anish Sarkar, Viet Chi Tran

The two-dimensional directed spanning forest (DSF) introduced by Baccelli and Bordenave is a planar directed forest whose vertex set is given by a homogeneous Poisson point process $\mathcal{N}$ on $\mathbb{R}^2$. If the DSF has direction $-e_y$, the ancestor $h(u)$ of a vertex $u \in \mathcal{N}$…

Affine hypersurfaces with constant sectional curvature

Miroslava Antić, Haizhong Li, Luc Vrancken, Xianfeng Wang

We use a new approach to study locally strongly convex hypersurfaces with constant sectional curvature in the affine space (Formula presented). We prove a nice relation involving the eigenvalues of the shape operator S and the difference tensor K of the affine hypersurface. This is achieved by…

Linear hyperbolic systems on networks: well-posedness and qualitative properties

Marjeta Kramar Fijavž, Delio Mugnolo, Serge Nicaise

We study hyperbolic systems of one-dimensional partial differential equations under general, possibly non-local boundary conditions. A large class of evolution equations, either on individual 1-dimensional intervals or on general networks, can be reformulated in our rather flexible formalism, which…

Representation Theory of Solvable Lie Groups and Related Topics

Jean Ludwig, Ali Baklouti, Hidenori Fujiwara

The purpose of the book is to discuss the latest advances in the theory of unitary representations and harmonic analysis for solvable Lie groups. The orbit method created by Kirillov is the most powerful tool to build the ground frame of these theories. Many problems are studied in the nilpotent…

Control of the Microstructure in Ceramics

Anne Leriche, Stuart Hampshire, Francis Cambier

Ceramic materials are commonly fabricated by powder processing and a subsequent heat treatment, which results in the elimination of about 40 vol% of porosity during the sintering step. The densification occurs at high temperature allowing atom diffusion in the solid state or through a liquid phase…

Enhancement of both optical and catalytic activity of copper-decorated porous silicon micro-particles

Abderrahmane Hamdi, Chohdi Amri, Rachid Ouertani, El Hadj Dogheche, Hatem Ezzaouia

To the best of our knowledge, this study is the first to investigate the effect of chemical vapour etching (CVE) combined with copper decoration on both the optical and catalytic activities of silicon micro-particles (SiμPs). After exposure to acid vapours emanating from a hot solution of hydrogen…

An optimal control problem governed by heat equation with nonconvex constraints applied to selective laser melting process

Tonia-Maria Alam, Serge Nicaise, Luc Paquet

This paper deals with a PDE-constraints optimal control problem applied to an Additive Manufacturing process, namely a selective laser melting. Here, we want to control the temperature gradient inside the domain during a fixed time of heating, by acting on the trajectory of the dynamic Gaussian…
