Abstract: | By using Leray-schauder degree theory and Wirtinger-type inequalities, the existence and uniqueness theorems for n th-order nonlinear ordinary differential equation u^( n ) = f( t, u, u′,…, u ^( n - 1 ) ) - e ( t ), 0 〈 t 〈 1, with n-point boundary conditions u^(n-3)(0) = 0, u^(i)(ηi) = 0, i = 0,1,2,…, n - 3, u^(n-3)(1) =0 are given. |
