Abstract:
A quasi-CR-mapping from a nilpotent Lie group
Open image in new window /></a> </div></figure> 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 <figure class=
Open image in new window /></a> </div></figure> 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.</div></td> </tr> <tr> <td align=
