Figure 2From: The existence of affine-periodic solutions for nonlinear impulsive differential equationsThe \((Q,T)\)-affine-periodic solution of system (27). The black line is the trajectory of \(x(t)\) for \(t\in(0,1]\), the red line corresponds to the trajectory of \(Qx(t)\) for \(t\in(0,1]\), and the green line corresponds to the trajectory of \(Q^{2}x(t)\) for \(t\in(0,1]\). It is easy to see that \(x(t)\) is a quasi-periodic solution of system (27)Back to article page
