UNIQUENESS OF POSITIVE SOLUTIONS OF A CLASS OF ODE WITH NONLINEAR BOUNDARY CONDITIONS RUYUN MA AND YULIAN AN Received 19 August 2004 and in revised form 27 January 2005 We study the uniqueness of positive solutions of the boundary value problem u + a(t)u + f (u) = 0, t ∈ (0,b), B1 (u(0)) − u (0) = 0, B2 (u(b)) + u (b) = 0, where 0
