在本論文中，我們將討論非線性常微分方程式之邊界值問題。在第一、二章中，我們探討下列廣義的Laplacian 邊界值問題：
(g(u''))''=f(t,u(t),u''(t)), 0<t<1,
u 屬於 B
其中B是一個適當的邊界條件。考慮不同的函數g與f，我們給定適當的充分條件而得到正解的存在性與唯一性。
在第三、四章中，我們考慮下列四階微分方程式之邊界
值問題：
u''+rf(t,u(t))=0, 0<t<1,
u 屬於 B''
其中B’是一個適當的邊界條件。利用定點定理，給定函數 的條件，我們將討論解的存在性與多重性。
In this dissertation, we will study nonlinear boundary value problems for some ordinary differential equations. In chapters 1 and 2, we study the following generalized Laplacian boundary value problems :
(g(u''))''=f(t,u(t),u''(t)), 0<t<1.
We establish the solution existence and uniqueness for the problem under different conditions concerning f(t,u(t),u''(t)).
In chapters 3 and 4, we consider the following nonlinear fourth order boundary value problems :
u''+rf(t,u(t))=0, 0<t<1.
Consider different conditions concerning f(t,u(t)), we study the existence and multiplicity of solutions by using fixed point theorem.
