论文摘要
我们使用重新归化组方法研究了DNA分子的Peyrard-Bishop模型中的孤子，该方法为扰动分析提供了系统的方式。在连续和离散的极限中进行了小幅度的扩展。我们回顾了连续模型的精确解决方案。此外，我们讨论了孤子解决方案的可靠性，并认为信封应以群体速度与以前的建议相反。
We investigate solitons in Peyrard-Bishop model of DNA molecule using Renormalization group methods which provide a systematic way for perturbation analysis. Small amplitude expansion is carried out in both the continuous and discrete limits. We review exact solution for the continuous model. Further, we discuss reliability of the solitonic solutions and argue that the envelope should propagate with a group velocity contrary to previous proposals.
