Einstein Metrics on solvable groups.
Équations aux différences associées à des groupes, fonctions représentatives.
Inspiré par un travail de J.-P. Bézivin et F. Gramain sur les systèmes d’équations aux différences, on caractérise les sous-groupes d’un groupe de Lie réel (resp. complexe) , pour lesquels toute fonction continue (resp. entière) telle que l’ensemble des -translatées engendrent un -espace vectoriel de dimension finie, engendrent aussi un -espace vectoriel de dimension finie par - translation. On fait le lien avec les systèmes d’équations aux différences à coefficients constants.
Equivalence of weak and viscosity solutions to the -Laplace equation in the Heisenberg group.
Estimates for derivatives of the Green functions on homogeneous manifolds of negative curvature.
Estimates for the mixed derivatives of the Green functions on homogeneous manifolds of negative curvature.
Estimates for the Poisson kernel on higher rank NA groups
We obtain an estimate for the Poisson kernel for the class of second order left-invariant differential operators on higher rank NA groups.
Estimates for the Poisson kernels and a Fatou type theorem applications to analysis on Siegel domains
This is a short description of some results obtained by Ewa Damek, Andrzej Hulanicki, Richard Penney and Jacek Zienkiewicz. They belong to harmonic analysis on a class of solvable Lie groups called NA. We apply our results to analysis on classical Siegel domains.
Estimates for the Poisson kernels and their derivatives on rank one NA groups
For rank one solvable Lie groups of the type NA estimates for the Poisson kernels and their derivatives are obtained. The results give estimates on the Poisson kernel and its derivatives in a natural parametrization of the Poisson boundary (minus one point) of a general homogeneous, simply connected manifold of negative curvature.
Example of a six-dimensional LCK solvmanifold
The purpose of this paper is to prove that there exists a lattice on a certain solvable Lie group and construct a six-dimensional locally conformal Kähler solvmanifold with non-parallel Lee form.
