Invariant operators on higher K-types.
Inversion de la transformation de Pompéiu dans le disque hyperbolique (Cas de deux disques).
In this paper we extend the result established for the euclidean space in [3] to the hyperbolic disk. This includes the reconstruction of a function defined in a fixed disk B(0,R) from its averages on disks of radii r1, r2 lying in B(0, R).
Is the maximal function of a Lipschitz function continuous?
Jets de fonctions differentiables sur le dual d'un groupe de Lie nilpotent.
John-Nirenberg lemmas for a doubling measure
We study, in the context of doubling metric measure spaces, a class of BMO type functions defined by John and Nirenberg. In particular, we present a new version of the Calderón-Zygmund decomposition in metric spaces and use it to prove the corresponding John-Nirenberg inequality.

estimates for functions of the Laplace-Beltrami operator on noncompact symmetric spaces. III
Let be a symmetric space of the noncompact type, with Laplace–Beltrami operator , and let be the -spectrum of . For in such that , let be the operator on defined formally as . In this paper, we obtain operator norm estimates for for all , and show that these are optimal when is small and when is bounded below .
