Nonperiodic Damped Vibration Systems with Asymptotically Quadratic Terms at Infinity : Infinitely Many Homoclinic Orbits

Abstract EN

We study a class of nonperiodic damped vibration systems with asymptotically quadratic terms at infinity.

We obtain infinitely many nontrivial homoclinic orbits by a variant fountain theorem developed recently by Zou.

To the best of our knowledge, there is no result published concerning the existence (or multiplicity) of nontrivial homoclinic orbits for this class of non-periodic damped vibration systems with asymptotically quadratic terms at infinity.
