Abstract

Let f(x,y)≢0f(x,y) \not\equiv 0 be a real-analytic planar function. We show that, for almost every R>0R>0 there exists an analytic 1-parameter family of vector fields XλX_{\lambda} which has {f(x,y)=0}BR((0,0))ˉ\{f(x,y)=0\} \cap \bar{B_R((0,0))} as a limit periodic set. Furthermore, we show that if f(x,y)f(x,y) is polynomial, then there exists a polynomial family with these properties.
