Abstract
A quasi-CR-mapping from a nilpotent Lie group
of step two to another such group satisfies a Beltrami-type system of partial differential equations which is usually not elliptic but subelliptic when the group
is strongly 2-pseudoconcave. We derive an integral representation formula for CR-mappings from a strongly 2-pseudoconcave nilpotent Lie group of step two to another such group and establish the Hölder continuity of ε-quasi-CR-mappings and the stability of CR-mappings between such groups.
