摘要
考虑由修正的Navier-Stokes方程产生的动力系统{Vt,t∈R,A},A是H中有界不变集.利用Sel定理证明了在f,1/α2,1/α3小的条件下,a∈A,其ω-极限集ω(a)是一周期运动,而且此周期运动是渐近稳定的.
Under the condition that f,1/α2,1/α3 are small enough for the modified NavierStokes equations,we prove that ωlimit set ω(a) consists of single periodic orbit,and the periodic motion is asymptotic stability for any point a∈A,,where A is bounded invariant set.Our proof is based on Sell′s theorem.
