Fast homoclinic solutions for damped vibration systems
with subquadratic and asymptotically quadratic potentials
Yiwei Ye
Abstract:
In this article, we study the nonperiodic damped vibration problem

where L(t) is uniformly positive definite for all
,
and W(t,x) is either subquadratic or asymptotically
quadratic in x as
.
Based on the minimax
method in critical point theory, we prove the existence and
multiplicity of fast homoclinic solutions for the above problem.
