Let the model be the generalized ellipsoid described in Section 2, equipped with the contact form $\vartheta$ defined in equation (polo). A CR map is said to preserve the Tanaka–We…

Let $S^n\subset\mathbb{C}^{n+1}$ and $S^N\subset\mathbb{C}^{N+1}$ be unit spheres, and let a CR map between them be $C^2$-smooth and non-constant. The codimension is $N-n$. Cima–Su…
