Unique determination of local CR-maps by their jets: a survey. (English) Zbl 1098.32018
The paper under review is a survey on the unique determination of local CR automorphisms, of which a significative sample is the following result, due to P. Ebenfelt, B. Lamel and D. Zaitsev [Finite jet determination of local analytic CR automorphisms and their parametrization by $$2$$-jets in the finite type case, preprint, 2001, http://arXiv.org/abs/math.CV/0107013, see also J. Geom. Anal. 14, No. 2, 241–265 (2004; Zbl 1076.32023)]: local biholomorphisms of a $$C^\omega$$ real hypersurface $$M \subset \mathbb C^2$$ at a point $$p \in M$$ are uniquely determined by their $$k$$-jets for some $$k$$ if and only if $$M$$ is not Levi-flat (near $$p$$). No proofs are given.Zbl 1076.32023
