摘要
In this paper, we consider the system where A(λ) is a linear transformation on Rn for each λ, α (λ,x) is an operator from R × Rn to Rn and λ is a real parameter. We examine large periodic solutions and drop the assumption of continuity of a(λ,x) near the origin. We consider what happens if a pair of eigenvalues of the linear part of the right hand side in (0. 1) crosses the imaginary axis for large where denotes the norm in Rn.
