Abstract
We construct a family of small analytic discs attached to Levi non-degenerate hypersurfaces in \(\mathbb{C }^{n+1}\), which is globally biholomorphically invariant. We then apply this technique to study unique determination problems along Levi non-degenerate hypersurfaces that are merely of class \(\mathcal{C }^4\). This method gives 2-jet determination results for germs of biholomorphisms, CR diffeomorphisms, as well as in the almost complex setting.
