Complex Points of Two-Dimensional Surfaces

Abstract:
We deal with complex points of two-dimensional surfaces. A short review of basic results about complex points of smooth surfaces in $\mathbb{C}^2$ is presented at the beginning. For algebraic surfaces, a formula is proved which expresses the number of complex points as the local degree of an explicitly constructible polynomial endomorphism.

Keywords:
Surface, grassmanian, complex point, Euler characteristic, mapping degree.
