Abstract:
In this paper, the existence of multiple positive solutions for a second-order threepoint boundary value problem is investigated. By using the fixed point index theorem, several sufficient conditions for the existence of at least one or infinte positive solutions are obtained.[著者文摘]
Key words:
three-point boundary value problem; fixed point index; positive solution; existence
