Directed harmonic currents near non-hyperbolic linearized singularities

Zhangchi Chen

Let $(D^{2}, F, {0})$ be a singular holomorphic foliation on the unit bidisc $D^{2}$ defined by the linear vector field \[ z \,\frac{\partial}{\partial z}+…

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…

Normal Forms for Rigid $C_{2, 1}$ Hypersurfaces $M^{5} \subset C^{3}$

Zhangchi Chen, Wei-Guo Foo, Joel Merker +1

Consider a $2$ -nondegenerate constant Levi rank $1$ rigid $C^{ω}$ hypersurface $M^{5} \subset C^{3}$ in coordinates $(z, ζ, w = u + i v)$ : \[ u = F\big(z,ζ,\bar{z},\bar…
