We present main ideas in the spectral and pseudospectral analysis of the damped wave equation $u_{tt} + 2a(x) u_t = \Delta_x u$ with an unbounded damping coefficient $a$, e.g.~$a(x) = x^2$, $x \in \mathbb R$. The …

On considère une version orientée acyclique du graphe d'Erdos-Rényi construit de la façon suivante : l'ensemble des sommets est {1,...,n}, et pour toute paire i < j, une arrête orientée de i vers j est présente …

Many modern applications of online changepoint detection require the ability to process high-frequency observations, sometimes with limited available computational resources. Online algorithms for detecting a change …

Un résultat de Kim et Koberda affirme que si M est une variété de dimension 1, et si $\alpha>1$ est une régularité donnée, alors il existe des sous-groupes de type fini de $\Diff^\alpha(M)$ qui ne se plongent …

In toric geometry, it is known that the geometric properties of a toric line bundle are closely related to a convex polytope, known as the Newton polytope. Based on the work of Okounkov, Lazarsfeld--Musta\c{t}\u{a} …

I will present an openness property of the existence of Hermite-Einstein metrics on blow-ups of compact complex manifolds.

We consider the dynamics of the composition of a rational function with a Galois action, acting on the Berkovich projective line of a non-archimedean field. Such an action can be considered as the analogue of …
