Comparing three possible hypoelliptic Laplacians on the 5-dimensional Cartan group via div-curl type estimates

Advanced Nonlinear Studies
On general Carnot groups, the definition of a possible hypoelliptic Hodge-Laplacian on forms using the Rumin complex has been considered in (M. Rumin, “Differential geometry on C-C spaces and application to the Novikov-Shubin numbers of nilpotent Lie ...

Controllability of systems of a nilpotent Lie group

, 1985
Sei W eine Teilmenge der Liealgebra L(G) einer zusammenhängenden Liegruppe G und sei S die durch Ext \({\mathbb{R}}^+W\) in G erzeugte Halbgruppe. Dann heißt das Paar (S,W) das durch W erzeugte System of G. Ein solches System heißt kontrollierbar, wenn \(S=G\) gilt. In diesem Fall läßt sich jedes Element \(g\in G\) in der Form \[ g=Exp t_ 1X_ 1...
