Existence of Almost Periodic Solutions For a Class of Nonlinear Duffing Equations
Duffing equations nonlinear almost periodic Stepanov almost periodic exponential dichotomy
2009/6/16
In this paper, we discuss the existence of almost periodic solutions for a class of nonlinear
Duffing equations. Some new theorems are established to ensure that the existence
of almost periodic sol...
