On structures of normal forms of complex points of small ${\mathcal{C}}^2$-perturbations of real $4$-manifolds embedded in a complex $3$-manifold

Tadej Starčič

We extend our previous result on the behavior of the quadratic part of a complex points of a small ${\mathcal{C}}^2$-perturbation of a real $4$-manifold embedded in a complex $3$-m…
