Estimates for the mixed derivatives of the Green functions on homogeneous manifolds of negative curvature

Electronic Journal of Differential Equations, 2004
We consider the Green functions for second-order left-invariant differential operators on homogeneous manifolds of negative curvature, being a semi-direct product of a nilpotent Lie group $N$ and $A=mathbb{R}^+$. We obtain estimates for mixed derivatives

Müntz–Szasz Theorems for Nilpotent Lie Groups

Journal of Functional Analysis, 1998
The classical Müntz-Szasz theorem says that for \(f\in L^2([0,1])\) and \(\{n_k\}^\infty_{k=1}\), a strict increasing sequence of positive integers, \[ \left(\int^1_0x^{n_j}f(x)dx=0,\forall j\Rightarrow f=0\right)\Leftrightarrow\sum^\infty_{j=1}{1\over n_j}=\infty.

Differential forms in Carnot groups: a variational approach

Bruno Pini Mathematical Analysis Seminar, 2011
Carnot groups (connected simply connected nilpotent stratified Lie groups) can be endowed with a complex of ``intrinsic'' differential forms. In this paper we want to provide an evidence of the intrinsic character of Rumin's complex, in the spirit of the
