Solvability of a fourth-order boundary value problem with periodic boundary conditions II

[摘要] Letf:[0,1]×R4→Rbe a function satisfying Caratheodory's conditions ande(x)∈L1[0,1]. This paper is concerned with the solvability of the fourth-order fully quasilinear boundaryvalue problemd4udx4+f(x,u(x),u′(x),u″(x),u‴(x))=e(x),   0
