摘 要:
本文研究作用在Cz周期函数空间上的微分算子u → u ″+ g (u),其中g(u)为连续有界函数.我们将证明上述微分算子的值域限制在周期函数空间的“超曲面”中。[著者文摘]

On the Range of the Second-Order Differential Operator with Bounded Perturbations

Abstract:
In this paper we will study the differential operator u → u ″+ g (u) which acts on the space of C2 periodic functions , where g (u) is a continuous bounded function which is complementary to the Landesman-Lazer case . It will be proved that the range of the differential operator above is a "twisted" strip in the space of periodic functions.[著者文摘]
