ABSTRACT

The multi-point boundary value problems of ordinary differential equations play a vital role in both theory and application, and as a consequence, have attracted a great deal of interest over the years. The application can be observed to model various phenomena in physics, biology, and engineering. However, in many situations, including the subjects just mentioned above, only positive solutions are meaningful. That is why people are particularly interested in positive solutions (Khan et al., 2019; Alves and Boudjeriou, 2020; Chammem et al., 2021).
