We consider the following system of differential equations Open image in new window , Open image in new window , Open image in new window together with Hermite boundary conditions Open image in new window , Open image in new window , Open image in new window , Open image in new window , where Open image in new window , Open image in new window for Open image in new window , and Open image in new window . By using different fixed point theorems, we offer criteria for the existence of three solutions of the system which are of "prescribed signs" on the interval Open image in new window .
