Abstract

Expanding on my former work along with the more recent work of Kasuya and Takase, we demonstrate that for a given link LML \subset M which is null-homologous in H1(M)H_1(M) and for any smooth oriented 2-plane field η\eta over LL there exists a smooth embedding F:MC3F:M \hookrightarrow \mathbb{C}^3 so that the set of complex tangents to the embedding is exactly LL and at each xLx \in L the holomorphic tangent space is exactly ηx\eta_x. Furthermore, we demonstrate how the "analyticity" of a complex tangent, as given by the Bishop invariant, may be determined exactly from the angle formed between the holomorphic complex line and the the curve of complex tangents.
