“…By Hsu and Zhao [10, Lemma 2.1], if h i > 0 (i = 1, 2, 3), then S has three axial fixed points, written as R 1 := (x * 1 , 0, 0), R 2 := (0, x * 2 , 0) and R 3 := (0, 0, x * 3 ). Besides, there are three planar fixed points for S in three coordinate planes under appropriate conditions (see [10, Theorem 2.2-2.4] or [26,Theorem 3.6]). First, we provide the existence result of carrying simplex for system (1.2).…”
