abstract = {For the  p-Laplace Dirichlet problem (where  φ(t)=t|t|p−2,  p&gt;1)   φ(u′(x))′+f(u(x))=0for−1&lt;x&lt;1,u(−1)=u(1)=0assume that  f′(u)&gt;(p−1)f(u)u&gt;0 for  u&gt;γ&gt;0, while  ∫uγf(t)dt&lt;0 for all  u∈(0,γ). Then any positive solution, with  max(−1,1)u(x)=u(0)&gt;γ, is non-singular, no matter how many times  f(u) changes sign on  (0,γ). The uniqueness of solution follows.}
