Infinitely many normalized solutions of $L^2$-supercritical NLS equations on noncompact metric graphs with localized nonlinearities

Pablo Carrillo, Damien Galant, Louis Jeanjean, Christophe Troestler

We consider the existence of solutions for nonlinear Schr\"odinger equations on noncompact metric graphs with localized nonlinearities. In an $L^2$-supercritical regime, we establish the existence of infinitely many solutions for any prescribed mass.

Virome release of an invasive exotic plant species in southern France

Oumaima Moubset, Denis Filloux, Hugo Fontes, Charlotte Julian, Emmanuel Fernandez, Serge Galzi, Laurence Blondin, Sélim Ben Chehida, Jean-Michel Lett, François Mesléard, Simona Kraberger, Joy M Custer, Andrew Salywon, Elizabeth Makings, Armelle Marais, Frédéric Chiroleu, Pierre Lefeuvre, Darren P Martin, Thierry Candresse, Arvind Varsani, Virginie Ravigné, Philippe Roumagnac

The increase in human-mediated introduction of plant species to new regions has resulted in a rise of invasive exotic plant species (IEPS) that has had significant effects on biodiversity and ecosystem processes. One commonly accepted mechanism of invasions is that proposed by the enemy release...

Densification of hydroxyapatite through cold sintering process: Role of liquid phase chemistry and physical characteristic of HA powder

Muthusundar Kumar, Mohamed Aymen Ben Achour, Marie Lasgorceix, Paulo Quadros, Rosica Mincheva, Jean-Marie Raquez, Anne Leriche

Hydroxyapatite is a well-known bioactive material widely employed in bone regeneration applications. Densifying hydroxyapatite at the nanoscale remains challenging with conventional sintering methods. This investigation focuses on the densification of commercially available nano-hydroxyapatite...

Discrete Gagliardo-Nirenberg inequality and application to the finite volume approximation of a convection-diffusion equation with a Joule effect term

Caterina Calgaro, Clément Cancès, Emmanuel Creusé

A discrete order-two Gagliardo–Nirenberg inequality is established for piecewise constant functions defined on a two-dimensional structured mesh composed of rectangular cells. As in the continuous framework, this discrete Gagliardo–Nirenberg inequality allows to control in particular the $L^4$ norm...

Aux sources historiques de l'exponentielle : une introduction en classe de première

Francois Goichot

On présente d'abord, historiquement, différents acteurs et différents contextes qui ont contribué à la découverte - ou l'invention - de ce qui est maintenant appelé fonction exponentielle. Un scénario est ensuite proposé, utilisant cette histoire pour introduire l'exponentielle en...
