Cesàro means of Fourier series on rotation groups

open access: yes, 1995
We study the CesAro means of Fourier series on rotation groups S0(3) and S0(4). On these two classical groups, we solve an open question recently posted in Harmonic analysis on classical groups [Springer-Verlag, Berlin, and Science Press, Beijing, 1991].

On the heat kernel of the Rumin complex and Calderón reproducing formula

open access: yesAnalysis and Geometry in Metric Spaces
We derive several properties of the heat equation with the Hodge operator associated with the Rumin’s complex on Heisenberg groups and prove several properties of the fundamental solution.

Singular integrals with exponential weights

open access: yes, 1996
We study the operators Vf (t) = V(f (r)w (r)) (t) w(t) where V is the Hardy-Littlewood maximal function, the Hilbert transform or Carleson operator.

General weighted Hardy-type inequalities related to Greiner operators

Rocky Mountain Journal of Mathematics, 2018
In this article, we present a general method that can be used to deduce weighted Hardy-type inequalities from a particular non-linear partial differential inequality in a relatively simple and unified way on the sub-Riemannian manifold R2n+1 = Rn×Rn×R ...
