%T Weak center for a class of Λ–Ω differential systems
%U http://acta.bibl.u-szeged.hu/75837/
%X In this paper, we give the necessary and sufficient conditions for a class of higher degree polynomial systems to have a weak center. As corollaries, we prove the correctness of the two conjectures about the weak center problem for the Λ–Ω differential systems.
