Asymptotic conditions for solving non-symmetric problems of third order nonlinear differential systems.
Convergence of solutions for a fifth-order nonlinear differential equation.
Further results for some third order differential systems with nonlinear dissipation
We formulate nonuniform nonresonance criteria for certain third order differential systems of the form , which further improves upon our recent results in [12], given under sharp nonresonance considerations. The work also provides extensions and generalisations to the results of Ezeilo and Omari [5], and Minhós [9] from the scalar to the vector situations.
Periodic solutions of certain third order differential systems with nonlinear dissipation
Results on Non-resonant Oscillations for some Nonlinear Vector Fourth Order Differential Systems
This paper presents vector versions of some existence results recently published for certain fourth order differential systems based on generalisations drawn from possibilities arising from the underlying auxiliary equation. The results obtained also extend some known works involving third order differential systems to the corresponding fourth order.
