Weak order for the discretization of the stochastic heat equation

Arnaud Debussche, Jacques Printems

In this paper we study the approximation of the distribution of $X_{t}$ Hilbert--valued stochastic process solution of a linear parabolic stochastic partial differential equation wri…

A Remark on Almost Umbilical Hypersurfaces

Julien Roth

In this article, we prove new stability results for almost-Einstein hypersurfaces of the Euclidean space, based on previous eigenvalue pinching results. Then, we deduce some compar…

Tsunami generation by dynamic displacement of sea bed due to dip-slip faulting

Denys Dutykh, Frederic Dias

In classical tsunami-generation techniques, one neglects the dynamic sea bed displacement resulting from fracturing of a seismic fault. The present study takes into account these d…

Eigenvalue pinching and application to the stability and the almost umbilicity of hypersurfaces

Jean-Francois Grosjean, Julien Roth

In this paper we give pinching theorems for the first nonzero eigenvalue of the Laplacian on the compact hypersurfaces of ambient spaces with bounded sectional curvature. As applic…

The group of automorphisms of a real rational surface is n-transitive

Johannes Huisman, Frédéric Mangolte

Let X be a rational nonsingular compact connected real algebraic surface. Denote by Aut(X) the group of real algebraic automorphisms of X. We show that the group Aut(X) acts n-tran…

Free Boolean algebras over unions of two well orderings

Robert Bonnet, Latifa Faouzi, Wiesław Kubiś

Given a partially ordered set $P$ there exists the most general Boolean algebra $F (P)$ which contains $P$ as a generating set, called the {\it free Boolean algebra} over $P$ . We st…

Sharp well-posedness results for the generalized Benjamin-Ono equation with high nonlinearity

Stéphane Vento

We establish the local well-posedness of the generalized Benjamin-Ono equation $\partial_{t} u + H \partial_{x}^{2} u \pm u^{k} \partial_{x} u = 0$ in $H^{s} (R)$ , $s > 1/2 - 1/ k$ for $k \geq 12$ a…

Poset algebras over well quasi-ordered posets

Uri Abraham, Robert Bonnet, Wieslaw Kubis

A new class of partial order-types, class $\gbqo^+$ is defined and investigated here. A poset $P$ is in the class $W^{+}$ iff the free poset algebra $F (P)$ is generated by a better…
