abstract = {<p style="text-align: justify;">The existence of positive solution is proved for a $(k, n − k)$ conjugate
boundary value problem in which the nonlinearity may make negative values and
may be singular with respect to the time variable. The main results of Agarwal et al.
(Agarwal R P, Grace S R, O&#39;Regan D. Semipositive higher-order differential equations. Appl. Math. Letters, 2004, 14: 201–207) are extended. The basic tools are the
Hammerstein integral equation and the Krasnosel&#39;skii&#39;s cone expansion-compression
technique.</p>},
