By employing the Deimling fixed point index theory, we consider a class of second-order nonlinear differential systems with two parameters (Ξ», Β΅) ∈ R 2 + \ {(0, 0)}. We show that there exist three nonempty subsets of R 2 + \ {(0, 0)}: Ξ“ , βˆ† 1 and βˆ† 2 such that R 2 + \ {(0, 0)} = Ξ“ βˆͺ βˆ† 1 βˆͺ βˆ† 2 and th
