Hi, I noticed that for some latex files the font used for the preview is of the right color (in my case white on black) while for others, it is not (black on black). As an example of the first beahavior I attached exple2.tex, and exple1.tex as an example of the second behavior. The problem seems to be coming from the packages loaded in the exple1.tex Best, F Emacs : GNU Emacs 21.2.1 (i586-pc-linux-gnu, X toolkit) of 2002-08-29 on alpha.maison.fr Package: CVS-1.169 current state: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Output from running `gs -h': GNU Ghostscript 6.51 (2001-03-28) Copyright (C) 2001 artofcode LLC, Benicia, CA.

Here, we consider the operator $\Pi_nV\Pi_n$ as acting on $\Pi_n L^2(\R^2)$ \end{Le} % \noindent{\bf Proof.} Let us first prove that it is upper semi-continuous. Fix $b_0>0$ and $\varepsilon\in(0,1)$. As $\Pi_n(b_0)V\Pi_n(b_0)$ and $\Pi_n(b_0)$ are bounded, there exists a sequence $(\varphi_l)_{l\in\N}$ of $\Coi$ functions such that $\Vert\Pi_n(b_0)\varphi_n\Vert=3D1$, and such that $\Vert(\Pi_n(b_0)V \Pi_n(b_0)-\mathcal{E}_n(b_0))\varphi_l\Vert\to0$. So, for some $l_0\in\N$, one has $\langle\Pi_n(b_0)V\Pi_n(b_0)\varphi_{l_0}, \varphi_{l_0}\rangle \leq\mathcal{E}_n(b_0)+\varepsilon/2$. On the other hand, $b\mapsto\Pi_n(b)\varphi_{l_0}$ is continuous as an $L^2(\R^d)$-valued function (as the the resolvent of the Landau model is strongly continuous as a function of $b$ (see e.g.~\cite{MR80k:35054}). Hence, there exists $\delta>0$ such that for $|b-b_0|<\delta$, one has $\Vert(\Pi_n(b)-\Pi_n(b_0))\varphi_{l_0} \Vert\leq\varepsilon/6$. This implies that, for $|b-b_0|<\delta$, if we set $\varphi=3D\Vert\Pi_n(b) \varphi_{l_0}\Vert^{-1}\Pi_n(b) \varphi_{l_0}$ then $\langle\Pi_n(b)V \Pi_n(b)\varphi,\varphi\rangle \leq\mathcal{E}_n(b_0)+\varepsilon$. Hence, for $|b-b_0|<\delta$, one has $\mathcal{E}_n(b)\leq\mathcal{E}_n(b_0)+\varepsilon$. % \par Let us now prove that it is lower semi-continuous. Therefore, we use a result of~\cite{MR87e:81039}, namely, % \begin{Th}[\cite{MR87e:81039}] \label{thr:1} Let $W$ be a bounded potential. If $[a,b]\cap\sigma(H_L(b_0)+W)=3D\emptyset$, then for $b$ sufficiently close to $b_0$, one has $[a,b]\cap\sigma(H_L(b)+W)=3D\emptyset$. \end{Th} % Consider the operator $H_L(b)+\lambda V$ for $\lambda$ positive small. Clearly as $V$ is bounded, its spectrum is contained in $\cup_{n\geq0}[2nb+b-\lambda|V|,2nb+b+\lambda|V|]$. For $\lambda|V|<b$, let $\mathcal{E}_n(b,\lambda)$ be the infimum of $H_L(b)+\lambda V$ restricted to the spectral interval $[2nb+b-\lambda|V|,2nb+b+\lambda|V|]$. The function $\lambda\mapsto\mathcal{E}_n(b,\lambda)$ is continuous. Moreover, perturbation theory (projecting onto the $n$-th Landau level) gives that, for $\lambda$ small, % \bibliographystyle{plain} \bibliography{biblio} % \end{document} %%% Local Variables:=20 %%% mode: latex %%% TeX-master: t %%% End:=20 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3D=3D=3DFile ~/exple2.tex=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D \documentclass[12pt]{article} \usepackage{amsthm} \usepackage{amssymb} \usepackage{amsfonts} \usepackage[leqno]{amsmath} \usepackage{french} \setlength{\topmargin}{0cm} \setlength{\textheight}{23cm} \setlength{\oddsidemargin}{0cm} % 2cm \setlength{\evensidemargin}{0cm} % 0cm \setlength{\textwidth}{16cm} %14cm \setlength{\parindent}{1cm} \pagestyle{plain} %%%%%%%%%%%% Commandes Maths %%%%%%%%%%%%% \newcommand{\car}{\mathbf{1}} \newcommand{\R}{\mathbb{R}} \newcommand{\Rd}{\mathbb{R}^d} \newcommand{\Spd}{\mathbb{S}^d} \newcommand{\T}{\mathbb{T}} \newcommand{\N}{\mathbb{N}} \newcommand{\Td}{\mathbb{T}^d} \newcommand{\Z}{\mathbb{Z}} \newcommand{\Zd}{\mathbb{Z}^d} \newcommand{\n}{\mathbb{N}} \newcommand{\C}{\mathbb{C}} \newcommand{\Cd}{\mathbb{C}^d} \newcommand{\Q}{\mathbb{Q}} \newcommand{\ch}{\mathrm{ch}} \newcommand{\sh}{\mathrm{sh}} \renewcommand{\th}{\mathrm{th}} \newcommand{\argsh}{\mathrm{argsh}} \newcommand{\argch}{\mathrm{argch}} \newcommand{\argth}{\mathrm{argth}} \newcommand{\argcoth}{\mathrm{argcoth}} \newcommand{\vers}{\operatornamewithlimits{\to}} \newcommand{\equ}{\operatornamewithlimits{\sim}} \newcommand{\D}{\displaystyle}=20 \newcommand{\Scp}{{\mathcal S}'} \newcommand{\Sc}{{\mathcal S}} \newcommand{\Coi}{{\mathcal C}_0^{\infty}} \newcommand{\esp}{\mathbb{E}} \newcommand{\pro}{\mathbb{P}} \newcommand{\Tr}{\text{tr}} \newcommand{\vol}{\text{Vol}} \newcommand{\F}{{\mathcal F}} %%%%%%%%%%%% Commandes TeX %%%%%%%%%%%%% \theoremstyle{definition} \newtheorem{ex}{Exercice} % \begin{document} \french \centerline{\bf test } % \vskip.5cm % \begin{ex} Soit $f$ une fonction {\`a} valeurs complexes sur $\Omega$, un domaine complexe.
