Tripled Periodic Boundary Value Problems of Nonlinear Second Order Differential Equations %K Ttripled periodic boundary value problems %K tripled fixed point theorem %K approximate tripled solutions %R %X The present paper proposes a new monotone iteration principle for the existence as well as approximationsof the tripled solutions for a tripled periodic boundary value problem of second order ordinary nonlineardifferential equations. An algorithm for the tripled solutions is developed and it is shown that the sequencesof successive approximations defined in a certain way converge monotonically to the tripled solutions of therelated differential equations under some suitable hybrid conditions. A numerical example is also indicatedto illustrate the abstract theory developed in the paper. %U https://www.cna-journal.com/article_89730_080227e466248d4899325814decf3b17.pdf
