Tangent cones at infinity

Luis Renato GonÃ§alves Dias, Nilva Rodrigues Ribeiro

Let $X \subset C^{m}$ be an unbounded pure $k$ -dimensional algebraic set. We define the tangent cones $C_{4, \infty} (X)$ and $C_{5, \infty} (X)$ of $X$ at infinity. We establish…

Symmetry defect of $n$ -dimensional complete intersections in $C^{2 n - 1}$

L. R. G. Dias, Z. Jelonek

Let $X, Y \subset C^{2 n - 1}$ be $n$ -dimensional strong complete intersections in a general position. In this note, we consider the set of midpoints of chords connecting a p…
