We consider boundary value problems for second order differential equations of the form ( x ' + g ( t , x , x ' ) ) ' = f ( t , x , x ' ) with the boundary conditions r ( x ( 0 ) , x ' ( 0 ) , x ( T ) ) + ϕ ( x ) = 0 , w ( x ( 0 ) , x ( T ) , x ' ( T ) ) + ψ ( x ) = 0 , where g , r , w are continuous functions, f satisfies the local Carathéodory conditions and ϕ , ψ are continuous and nondecreasing functionals. Existence results are proved by the method of lower and upper functions and applying the degree theory for α -condensing operators.
