Affine Homogeneous Surfaces with Hessian rank 2 and Algebras of Differential Invariants

Zhangchi Chen, Joël Merker

Consider a graphed holomorphic surface $u = F (x, y)$ in $C_{x, y, u}^{3}$ under the action of the affine transformation group $A (3)$ . In 1999, Eastwood and Ezhov obtained a list…

On Differential Invariants of Parabolic Surfaces

Zhangchi Chen, Joël Merker

The algebra of differential invariants under $S A_{3} (R)$ of generic parabolic surfaces $S^{2} \subset R^{3}$ with nonvanishing Pocchiola $4^{th}$ invariant $W$ i…
