摘要
利用上下解的方法[1,2] ,讨论了非线性四阶常微分方程y(4) = f(t,y ,y′,y″,y)( * ) 满足边界条件:y(a) = a0 ,y′( a) = a1 ,g(y″(a) ,y(a)) = 0 ,h(y(c) ,y′(c) ,y″(c) ,y(c)) = 0 的两点边值问题解的存在性,其中函数f,g ,h
In this paper,the authors use the methods in[1,2]to study the existence of solutions of two point boundary value problems for nonlinear fourth order differential equation y (4) =f(t,y,y′,y″,y)with the boundary conditions y(a)=a 0,y′(a)=a 1,g(y″(a),y(a))=0,h(y(c),y′(c),y″(c),y(c))=0,where functions f,g and h are continuous functions with certain monotone conditions.
