Abstract: Les groupoïdes de Lie sont des objets qui font le lien entre les variétés différentiables et les groupes de Lie, qui en sont des cas particuliers. Nous allons décrire la structure de Poisson sur le dual de l'algébroïde de Lie d'un groupoïde de Lie G, et formuler une conjecture de type Kirillov reliant l'espace des feuilles symplectiques de cette variété de Poisson avec les représentations unitaires de la C^*-algèbre de G. Nous illustrerons ce principe à l'aide de quelques exemples.
Dominique is a regular visitor to our laboratory LAMHA at the Mathematics Department of the Faculty of sciences of Sfax. His last visit took place in December 2017 and right after he attended and gave an invited talk at the fifth Tunisian-Japanese Conference of geometric and harmonic analysis on homogeneous spacesTJC2017.
December 17- 21, 2018. Invited talk: Nouveaux exemples d'actions affines propres sur R^n Abstract: Les actions propres de groupes discrets sur R^n par transformations affines ont été beaucoup étudiées en lien avec la théorie des pavages de R^n. Lorsque l’action est cocompacte, la conjecture d’Auslander affirme que le groupe discret doit être virtuellement résoluble. Lorsque l’action n’est pas cocompacte, il existe des groupes discrets non virtuellement résolubles agissant proprement sur R^n dès que n>2 : les premiers exemples ont été construits par Margulis en 1983. Jusqu'à présent, on ne connaissait d'exemple d'action affine propre irréductible sur R^n que pour des groupes virtuellement résolubles ou virtuellement libres. Nous construisons des exemples pour tous les groupes de Coxeter à angles droits. La preuve consiste, pour G=O(p,q), à construire des actions affines propres sur l’algèbre de Lie de G comme « versions infinitésimales » d’actions propres sur (GxG)/Diag(G). Travail en commun avec Jeffrey Danciger et François Guéritaud.

I also give the form of solutions on algebraic structures such as semi-groups and monoids.
December 16-19, 2019: Djerba, Conference TJC2019 in honour of Takaaki Nomura. Invited talk 1: Visible actions on complex Heisenberg homogeneous spaces and geometric criterion for multiplicity-freeness of representations. The abstract is available here.
September 14-19, 2018. Invited talk 2: Introduction to visible actions on complex manifolds. Abstract: The notion of (strongly) visible actions on complex manifolds has been introduced by T. Kobayashi (2004, 2005) to give an unified explanation of multiplicity-freeness property of representations of Lie groups which are realized in holomorphic sections of Hermitian holomorphic vector bundles (Propagation theorem of multiplicity-freeness property for holomorphic vector bundles). First of this lecture, we summarize a relationship between multiplicity-free representations and visible actions. Next, we explain the notion of (strongly) visible actions on complex manifolds. In particular, we show their elementary examples as many as possible. They include such as the torus action on the complex vector space, the SO(2)-action on the complex upper-half plane and the one coming from the diagonalizable of complex matrices.
Invited talk 3: Recent study on a classification of strongly visible actions. Abstract: Many examples of (strongly) visible actions has been found in connection with multiplicity-free representations. Then, we expect that multiplicity-free representations realized in holomorphic sections have strongly visible actions on the base spaces. In this aspect, we explain the recent study on the classification problem of strongly visible actions. In this talk, we treat complex manifolds such as :
- Hermitian symmetric spaces,
- complex vector spaces,
- flag varieties,
- nilpotent orbits in complex simple Lie algebras.
- Hermitian symmetric spaces,
- complex vector spaces,
- flag varieties,
- nilpotent orbits in complex simple Lie algebras.

September 5-10, 2018. Invited talk: Harmonic analysis for Frobenius Lie algebras. Abstract: A real Frobenius Lie algebra is characterized as the Lie algebra of a Lie group admitting open coadjoint orbits. In the context of the orbit method, such open coadjoint orbits are expected to correspond to square-integrable unitary representations. We pose a conjecture about the relation between the formal degrees of the representations and the Pfaffian of the Frobenius Lie algebra.
