Con.ider the p.lyn.m.al differen.ial system.of degree m.of the form.x=-y(1+μ(a_(2)x-a_(1)y))+x(v(a_(1)x+a_(2)y)+Ω_(m.1)(x,y)),y=x(1+μ(a_(2)x-a_(1)y))+y(v(a_(1)x+a_(2)y)+Ω_(m.1)(x,y)),whereμan.νare real n.m.ers such that(μ^(2)+v^(2))(μ+v(m.2))(a_(1)^(2)+a_(2)^(2))≠m.2 an.Ω_(m.1)(x,y)is a hom.gen.us p.lyn.m.al of degree m.1.A con.ecture,stated in.*** Equation. 2019,suggests that when.=1,this differen.ial system.has a weak cen.er at the origin.if an. on.y if after a con.en.en. lin.ar chan.e of variable(x,y)→(X,Y)the system.is in.arian. un.er the tran.form.tion.X,Y,t)→(−X,Y,−t).For every degree m.we p.ove the exten.ion.of this con.ecture to an. value ofνexcep. for a fin.te set of values ofμ.
