强一致收敛下弱几乎周期点和周期序列跟踪性的研究

On the Weakly Almost Periodic Point and the Periodic Sequence Shadowing Property Under Strongly Uniform Convergence

  • 摘要: 在强一致收敛下,研究了弱几乎周期点和周期序列跟踪性,得到弱几乎周期点和周期序列跟踪性的若干结论: (1)设序列映射fn强一致收敛于等度连续映射f,且点列xk是每个映射fn的弱几乎周期点. 若\mathop \lim \limits_k \to \infty x_k = x,则xf的弱几乎周期点. (2)若序列映射fn强一致收敛于等度连续映射f,则limsup W(fn)⊂W(f). (3)若fn具有fine周期序列跟踪性,则f具有周期序列跟踪性.

     

    Abstract: The weakly almost periodic point and the periodic sequence shadowing property are studied under strongly uniform convergence. Some conclusions about them are obtained. First, let the sequence map fn converge strongly uniformly to the equicontinuous map f and the sequence of pointsxkbe the weakly almost periodic point of every map fn. If \mathop \lim \limits_k \to \infty x_k = x, then the point x is the weakly almost periodic point of the map f. Second, if the sequence mapfnconverges strongly uniformly to the equicontinuous map f, then limsup W(fn)⊂W(f). Third, if fn has the fine periodic sequence shadowing property, then f has periodic sequence shadowing property.
