Mes intérets de recherche se trouvent dans le domaine des équations aux dérivées partielles. Surtout je travaille sur des questions en calcul des variations. En particulier, je m'intéresse à l'élasticité non-linéaire, et à des problèmes variationels qui contiennent en même temps des aspects physiques et géométriques.

in fluid dynamics, magnetic Sobolev spaces and semi-linear elliptic problems.

I am interested in applying categorical methods to the study of groups and filtrations on them. Precisely, by "groups", I mean mainly some infinite groups, often with a topological flavor, such as braid groups and their generalizations, or automorphisms of free group. And by "filtrations", I mean lower central series of groups, or filtrations similar to them.

Pierre-Alain Jacqmin
My main research interests lie in Category Theory, and more specifically in Categorical Algebra and Universal Algebra. My aim is to deeper understand algebraic categorical properties such as the Mal'tsev, unital or semi-abelian properties; in particular via some embedding theorems or preservation under the cofiltered limit completion. I am also interested in internal groupoids, weak equivalences and their bicategory of fractions as well as in finiteness spaces and generalized rings of power series.

My research has spanned several areas of mathematics, however always centered around the study of the representations of the given object. Nowadays my focus is on finite dimensional representations of quantum affine algebras via geometric realisations. Hereby the angle is additive and monoidal categorification of an underlying cluster algebras.
Earlier my research focused on integral representation theory of finite groups, via connections to arithmetic groups. The latter can be thought as the integer points of semisimple linear algebraic groups of which the group of units of the integral group ring is an example of. The overarching quesiton here is which properties of the finite group can reconstructed out of the geometric group theoretical properties of the simple factors of the overlying algebraic group.

My main research interests are category theory and homological algebra. I am particularly interested in the interplay of these fields with algebraic geometry in order to approach noncommutative algebraic geometry, where both abelian categories and enhancements of triangulated categories are used as models for noncommutative spaces. I am therefore interested in many different related areas: topos theory, localizations and categories of fractions, algebraic categories, triangulated and dg categories, infinity-categories, deformation theory…

My PhD-topic is to develop a non-abelian theory of spectral sequences. Double semi-simplicial groups have certain spectral sequences associated to them. The motivating question is how much can we generalize this to the semi-abelian context.

I study (infinite) discrete groups. My interests include, but are not limited to : the representation theory of lattices in non-discrete groups ; the geometry of low dimensional complexes of groups ; approximation by finite groups ; local-global phenomena. Currently, my focus is set on a family of discrete groups acting on euclidean buildings. I would like to better understand which features they have in common, but also for each their own specificities. Some keywords : geometric group theory, representation theory, harmonic analysis, algebraic groups over local fields.

Did my masters thesis in topos theory.
Currently writing about Lyapunov theory in categorical terms, specifically the converse lyapunov theorem that a system with an equilibrium point must have a corresponding "energy function" (lyapunov fucntion, ie a function that decrease on trajectory and "sufficiently" smooth) that serve as a certificate for the stability.

The goal of the research is to explore the exactness properties of the category of preordered groups and of preordered abelian groups, with particular attention to non-additive torsion theories in these categories. We will then develop a new approach to non-abelian homology of preordered groups. A generalization of some of these results to preordered semi-abelian algebras will also be considered.

I work on the interplay between knot theory and higher representation theory. More precisely, I'm interested in an invariant of knots called odd Khovanov homology, which can be thought as a categorification of the Jones polynomial. I try to understand it through the categorification of (the representation theory of) quantum algebras.

My PhD research concerns higher categorical Galois theory in the context of certain algebraic structures of interest called quandles (a notion of symmetry which is used in knot theory and geometry). The category of quandles is algebraic by nature, but features interesting geometrical properties. This provides an interesting context for the study and illustration of higher categorical Galois theory and related meaningful notions of homotopy. Key words: higher categorical Galois theory, racks and quandles, centrality, commutators, higher coverings.
