WebThe first part of Hilbert’s sixteenth problem[9], broadly interpreted, asks us to study the topology of real algebraic varieties. However, the case of non-singular plane curves is already very difficult. Let f(xO,x,,xZ) be a real homogeneous polynomial of degree d; we set X = {(Xi) E CP21f(&J,J2) = 01 WebFeb 16, 2012 · The article reviews recent developments and techniques used in the study of Hilbert’s 16th problem where the main focus is put on the subclass of polynomial vector fields derived from the Liérd equations.

WebHilbert's 16th problemwas posed by David Hilbertat the Parisconference of the International Congress of Mathematiciansin 1900, as part of his list of 23 problems in mathematics. [1] The original problem was posed as the Problem of the topology of algebraic curves and surfaces(Problem der Topologie algebraischer Kurven und Flächen).
