Abstract: 
Values of $\lambda$ are determined for which there exist solutions in a
cone of the $n^{th}$ order nonlinear differential equation, 
 $$u^{(n)} = \lambda a(t) f(u)\,,\quad  0 < t < 1\,,$$ 
satisfying  the multipoint boundary conditions, 
 $$u^{(j)}(a_i) = 0\,,\quad 0\leq j\leq n_i -1\,,\quad 1 \leq i \leq k\,,$$ 
where $0 = a_1 < a_2 < \cdots < a_k  = 1$, and $\sum _{i=1}^k n_i = n$, 
where $a$ and $f$ are nonnegative valued, and where both 
 $\lim\limits_{|x| \to 0^+} f(x)/|x|$ and 
 $\lim\limits_{|x| \to\infty} f(x)/|x|$ exist.
