abstract = {<p style="text-align: justify;">This paper deals with the existence of positive solutions to a singular
fourth order coupled system with integral boundary conditions. Since the nonlinear
terms $f$, $g$ may change sign or be singular at $t = 0$ or $t = 1$, the authors make a
priori estimates to overcome some difficulties and apply Guo-Krasnoselskii fixed point
theorem to prove the existence of solutions of the system under suitable assumptions.
Finally, some examples to illustrate the main results are given.</p>},
