Abstract
Sufficient and necessary conditions are found for the existence of a positive periodic solution to the Duffing type equation uâ²â²=p(t)u+q(t,u)u.The results obtained are compared with facts well known for the autonomous Duffing equation yâ²â²+ayâby3=0.Uniqueness of solutions and possible generalizations are discussed, as well.
