Operator algebras are self-adjoint subalgebras of the bounded operators on a Hilbert space and divide into two main classes: C∗-algebras and von Neumann algebras, according to whether one demands that they are closed in the norm topology or the weak operator topology.

Mathematical Developments in Geophysical Fluid Dynamics
Geophysical Fluid Dynamics covers a wide range of applications in atmospheric and oceanic sciences with direct connections to the challenges of climate change. Historically studied by physicists and applied mathematicians, rotating fluids have been the subject of many recent results involving the analysis of PDEs. However, exchanges between these communities remain relatively rare and isolated.
Illustration as a Mathematical Research Technique
La compréhension des mathématiques se construit de multiples façons. Parmi celles-ci, l'illustration accompagne la recherche et en est l'outil depuis qu'elle existe. Nous utilisons le terme « illustration » pour englober les nombreuses façons de donner une forme physique ou une expérience à une idée mathématique, y compris la visualisation par ordinateur, l'impression en 3D et la réalité virtuelle, entre autres.
