              Electronic Structures

5. 초록 In the self-consistent calculations of electronic structures, mixing schemes are widely used to improve the convergence of the iteration. With a fixed-point problem arisen from such a calculation, I will review on the past and present results on deterministic mixing schemes such as the simple mixing and Anderson mixing. Secondly, I will give an overview of the simple mixing scheme towards convergence in mean-square and stochastic stability based on the Lyapunov functional approach. I also hope to describe about our results on convergence and stability of general mixing schemes.
