Intersection theory in complex analytic geometry

Piotr Tworzewski (1995)

Annales Polonici Mathematici


We present a construction of an intersection product of arbitrary complex analytic cycles based on a pointwise defined intersection multiplicity.

Polynomial systems: a lower bound for the weakened 16th Hilbert problem.

Chengzhi Li, Weigu Li, Jaume Llibre, Zhifen Zhang (2001)

Extracta Mathematicae


In this paper we provide the greatest lower bound about the number of (non-infinitesimal) limit cycles surrounding a unique singular point for a planar polynomial differential system of arbitrary degree.
