Results dealing with the behavior of the integrated density of states of random divergence operators
Hatem Najar
In this paper we generalize and improve results proven for acoustic operators in \cite{jmp,long}. It deals with the behavior of the integrated density of states of random divergenc…

About a result of S.M. Kozlov
Hatem Najar
We give an alternative proof and improve upon a result of S.M. Kozlov \cite{ko}. It deals with the asymptotic of the integrated density of states of the acoustic operator $\display…
