Isochronicity conditions for some planar polynomial systems
Résumé
We study the isochronicity of centers at $O\in \mathbb{R}^2$ for systems $\dot x=-y+A(x,y),\;\dot y=x+B(x,y)$, where $A,\;B\in \mathbb{R}[x,y]$, which can be reduced to the Liénard type equation. Using the so-called C-algorithm we have found 27 new multiparameter isochronous centers.
