Our purpose of this paper is to study positive solutions of Lane-Emden equation -?u=Vup in RN0 perturbed by a non-homogeneous potential V when p ? [pc,N+2N-2), where pc is the Joseph-Ludgren exponent. When p ? (NN-2,pc) the fast decaying solution could be approached by super and sub solutions, which are constructed by the stability of the k-fast decaying solution wk of -?u = up in RN \ 0 by authors in [9]. While the fast decaying solution wk is unstable for p ? (pc,N+2N-2) so these fast decaying solutions seem not able to disturbed like (0.1) by non-homogeneous potential V. A surprising observation that there exists a bounded sub solution of (0.1) from the extremal solution of -?u=uN+2N-2 in RN and then a sequence of fast decaying solutions and slow decaying solutions could be derived under appropriated restrictions for V. © 2021 Yong Ma et al., published by De Gruyter 2021.
