Nonexistence of radially symmetric nonnegative solutions for a class of semi-positone problems
We study the radially symmetric non-negative solutions for the boundary value problemwhere >. > 0, f(O) < 0 (semi-positone) and f superlinear.We establish that there exists a >.0 > 0 such that for >. > >.0 there are no non-negative solutions.
