In this paper, we consider the existence of positive solutions to the following semipositone (k, nk) conjugate eigenvalue problems (SCEP): where n โฅ 2, 1 < k < n -1 and ฮป > 0 is positive parameter. The nonlinear function f may change sign for 0 < t < 1, i.e., we allow that the nonlinear term f is b
