摘要
In this paper, we study the existence problem of anti-periodic solutions for the following first-order nonlinear evolution equation: {u'(t) + Au(t) + F(t,u(t)) = 0, t is an element of R, {u(t + T) = -u(t), t is an element of R, in a Hilbert space H, where A is a self-adjoint operator and F is a continuous nonlinear operator. An existence result is obtained under assumptions that D(A) is compactly embedded into H and F is anti-periodic and bounded by a L-2 function. Furthermore, anti-periodic solutions for second-order equations are also studied.
