The aim of these notes is to give a presentation of extracts (with some corrections or modifications) of Helffer-Kerdelhué-Sjöstrand [18] translated from the french into english devoted to a better understanding of the structure of the Hofstadter butterfly for any λ > 0. This was at the time based on a conjecture which is now proven [3] for λ ∈ (0, 1) due to its equivalence with the Dry.

The two-dimensional Schroedinger operator with a uniform magnetic field and a periodic zero-range potential is considered and shows the existence of parts of Cantor structure in the spectrum for special values of the magnetic flux.

Douglas Hofstadter (1945-) is a peculiar scholar : a Pulitzer-prize winner and a specialist in cognitive science, he is nevertheless quite fond of translation, to the point of practicing (and studying) it in several publications since 1997. Our essay focuses on his latest work in this field, That Mad Ache / Translator, Trader (2009).

The simplest model for such phenomena is described by the discrete Harper operator; Azbel [1], Hofstadter [2], and Wannier [3] were the first scientists who studied this model and discovered the fractal structure of its spectrum..

The Hofstadter butterfly plays an important role in the theory of the integer quantum Hall effect and the theory of topological quantum numbers . History The first mathematical description of electrons on a 2D lattice, acted on by a perpendicular homogeneous magnetic field, was studied by Rudolf Peierls and his student R. G. Harper in the 1950s.
