Nonlinear n-Order m-Point Semipositive Boundary Value Problems and Applications
In our paper, we consider the positive solutions of the nonlinear n-order m-point semipositive BVP. In this BVP equation, we allow that f can change the symbol for 0<t<1; by using the fixed point index theory, the existence of positive solutions and many positive solutions are obtained under t...
