We consider the existence of affine-periodic solutions to the nonlinear ordinary differential equation:

$\label {ae} x^{\prime }=f(t,x) $(0.1)

in ℝn, where f is continuous and ensures the existence and uniqueness of solutions with respect to initial conditions, and there exist T > 0 and QGL(n) such that:

$\label {me} f(t+T,x)=Qf(t,Q^{-1}x) \quad \forall (t,x)\in \mathbb R\times \mathbb R^{n}. $(0.2)

We utilize the asymptotic method to study the existence of Q-affine T-periodic solutions of Eqs. 0.1–0.2. Affine-periodic solutions exhibit a rich variety of complex spatiotemporal pattern, might be periodic, anti-periodic, quasi-periodic, and even unbounded spiral motions.

渐近方法的仿射周期解

我们考虑了非线性常微分方程的仿射周期解的存在:

$ \ label {ae} x ^ {\ prime} = f(t,x)$(0.1)

在ℝ Ñ,其中˚F是连续的,并确保解决方案的存在唯一相对于初始条件,并且存在Ť > 0且Qģ大号Ñ),使得:

$ \ label {me} f(t + T,x)= Qf(t,Q ^ {-1} x)\ quad \ forall(t,x)\ in \ mathbb R \ times \ mathbb R ^ {n} 。$(0.2)

我们利用渐近方法研究方程的Q-仿射T-周期解的存在性。0.1-0.2。仿射周期解表现出多种复杂的时空模式,可能是周期性的,反周期的,准周期的,甚至是无界的螺旋运动。
