Streszczenie
We first study the behavior of weights on a simply connected nilpotent Lie group $G$. Then for a subalgebra $A$ of $L^1(G)$ containing the Schwartz algebra ${\mathcal S}(G)$ as a dense subspace, we characterize all closed two-sided ideals of $A$ whose hull reduces to one point which is a character.
