摘要
本文给出了单峰函数符号序列即由字母R.L.C组成的一类序列的一些性质,推广了Collet和Eckmann的文章中的某些结论,证明了关于单峰函数的点的旅程的一些命题,并对作者的另一篇文章中的一个主要定理作了进一步的讨论。
Unimodal symbols are the letters R,L and C. In this
paper, some properties of sequences of unimodal symbols are given,
some conclusions in a paper written by Collet and Eckmann are generalized,
and several propositions about itineraries of points in unimodal functions
are proved. These properties and propositions are applied in another
paper of the authors.Moreover,further discussions about a main
theorem in that paper of the authors are done.
