| Abstract: | In this paper,the existence of a positive solution for a P-laplace equation group with boundary value condition is investigated.An integral equation equivalent to the boundary value problem is constructed.An operator is defined through the integral equation.A fixed point of the operator is obtained by fixed point theorem of cone expansion and compression of norm type.Thus the existence of positive solutions of boundary value problems is proved. |
