摘要：

Our aim is to give a result on Gevrey regularity for Gevrey vectors (in L-2-space) for Hormander's operators and a very short survey of some works in the area, particularly recent ones on systems of vector fields or the partial differential operators of second-order associated to these systems. We also recall the regularity results in the case of elliptic operators or of principal type.
