Fatma Sassi, Ameni Gargouri, Lubomir Gavrilov, Bassem Ben Hamed

摘要:

我们证明了可逆三次系统的中心集,接近于对称哈密顿系统$x'=y, y'= x-x^3$,在参数空间中有两个余维2的不可约分量。其中一个对应于Hamilton层,另一个对应于适当的线性系的多项式拉回系统

英文摘要:

We show that the center set of reversible cubic systems, close to the symmetric Hamiltonian system $x'=y, y'= x-x^3$ has two irreducible components of co-dimension two in the parameter space. One of them corresponds to the Hamiltonian stratum, the other to systems which are polynomial pull back of an appropriate linear system
