If you have a question about this talk, please contact Yuzhao Wang. Let $G$ be a noncompact nonunimodular Lie group and $\{X_1, ...,X_q\}$ a set of left-invariant vector felds which satisfy the Hormander’s condition.
Defne the subLaplacian $\Delta = – \sum_{i=1} In particular, we shall discuss Sobolev embeddings and algebra properties of the spaces £Lp_\alpha$. Such properties are useful for applications to well-posedness results for semilinear differential equations associated with the subLaplacian on the group. The results discussed in the talk are joint work with Tommaso Bruno, Marco M. Peloso and Anita Tabacco [1, 3]. The counterpart of our results on unimodular Lie groups were obtained by Coulhon, Russ and Tardivel-Nachef [2]. References [1] T. Bruno, M.M. Peloso, A. Tabacco and M.
