We provide a sharp criterion in term of generalized principal eigenvalues for existence/non-existence of positive solution of (P-beta) in suitable classes of functions. Uniqueness result for (P-beta) in those classes is also derived. Under additional conditions on Phi, we further show that: i) either for every beta >= 0 nonexistence phenomenon occurs, ii) or there exists a threshold value beta* > 0 in the sense that for every beta is an element of [0, beta*) existence and uniqueness phenomenon occurs and for every beta >= beta* nonexistence phenomenon occurs. In the latter case, we study the limits, as beta -> 0 and beta -> beta*, of the sequence of positive solutions of (P-beta). Our results are new even in the case p = 2. ER -
