| Abstract: | The existence of positive solutions of boundary value problemx″(t)+λa(t)f(x(t),y(t))=0y″(t)+λb(t)g(x(t),y(t))=0x(0)=x(1)=y(0)=y(1)=0is investigated where f and g are functions from R+×R+ into R+; and a,b are functions from 0,1] into R+. All functions are assumed to be continuous, and some growth conditions are imposed on f and g. We get some results about the existence of positive solution. |
