By employing the Deimling fixed point index theory, we consider a class of second-order nonlinear differential systems with two parameters (ฮป, ยต) โˆˆ R 2 + \ {(0, 0)}. We show that there exist three nonempty subsets of R 2 + \ {(0, 0)}: ฮ“ , โˆ† 1 and โˆ† 2 such that R 2 + \ {(0, 0)} = ฮ“ โˆช โˆ† 1 โˆช โˆ† 2 and th
