For both systems we investigate that they have the same Floquet exponents. The relation between monodromy matrices of both systems is also presented. Classification of solution according to the nature of Floquet exponent is established. Then according to these results, we study the stability and bifurcation phenomenon of our differential algebraic equation systems.}, number={3}, journal={Journal of Zankoy Sulaimani - Part A}, year={2015}, month={Apr.}, pages={73–86} }
