| Abstract 摘要 | The motivation of this work is to generalize the Thouless's formula of the bandwidth of the Hofstadter spectrum(which is related to the Catalan's constant) to higher bandwidth moments. This talk will show a closed expression of the n-th moment of the Thouless bandwidth formula in terms of polygamma, Zeta and Euler numbers is obtained. |
