Abstract:
We provide a new way of simultaneously parametrizing arbitrary local CR maps from real-analytic generic manifolds $M\subset \mathbb {C}^N$ into spheres $\mathbb {S}^{2N’-1}\subset \mathbb {C}^{N’}$ of any dimension. The parametrization is obtained as a composition of universal rational maps with a holomorphic map depending only on $M$. As applications, we obtain rigidity results of different flavours such as unique jet determination and global extension of local CR maps.References
