Positive solutions for some semi-positone problems via bifurcation theory
Bifurcation Theory is used to prove the existence of positive solutions of some classes of semi-positone problems.extensively studied; see, e.g., [3], [10], [11], and the survey [1].On the contrary we deal here with the so called semi-positone (or non-positone)problem, when f is such thatRecently some existence results concerning semi-positone problems …
