  • Equation (2): Let's unpack this. It's claimed that, for an irreducible projective variety $ V \subset \mathbb{P}^r $, there exists a hypersurface $ H = V(\varphi) \subset \mathbb{P}^{k+1} $ such that, for an appropriate choice of coordinates on $ \mathbb{P}^r $, there is a map $ H \rightarrow \mathbb{P}^r $ sending $ [t_1 : \cdots : t_{k+2}] $ to $ \left[\frac{\partial \varphi}{\partial t_1} t_1 : \frac{\partial \varphi}{\partial t_1} t_2 : \cdots : \frac{\partial \varphi}{\partial t_1} t_{k+2} : \psi_1\left(\vec{t}\right) : \cdots  :\psi_{r-k-1} \left(\vec{t}\right)\right] $ for some homogeneous polynomials $ \psi_i $ which is a dominant map to V. That is, this is some sort of implicit function theorem.
