摘要:In the landmark paper [Johnson and Moser, CMP-1982], the authors used the rotation number approach to establish the spectrum of the one-dimensional Schrödinger operator with almost periodic potentials. In this talk, I will present their paper, specifically on how to introduce the concept of rotation numbers. As an entry point, a picture of rotation numbers will be demonstrated. At last, I will discuss our thought on  their paper.
