Abstract

Given a smooth complex variety XX, an algebraically skew embedding of XX is an embedding of XX into a complex projective space PN\mathbb{P}^N such that for any two points x,yXx,y\in X, their embedded tangent spaces in PN\mathbb{P}^N do not intersect. In this work, we establish an upper bound and a lower bound of the minimal dimension NN such that there exists an algebraically skew embedding into PN\mathbb{P}^N in terms of the dimension of the given smooth variety XX. Then we further classify the algebraic curves in terms of their minimal skew embedding dimensions, and apply the same technique to other one-parameter family of lines.
