Der Autor diskutiert in seinem Aufsatz kritisch den Friedensvertrag von Lomé, der am 7. Juli 1999 offiziell den bewaffneten Konflikt in Sierra Leone beendete. Nach einer kurzen Zusammenfassung der allgemeinen Regelungen des Vertrags stellt der Autor die in Artikel 9 des Abkommens vorgesehene Generalamnestie den bindenden Grundsätzen des internationalen Rechts gegenüber. Internationale Verbrechen, wie Völkermord, Kriegsverbrechen oder Folterung sind als Verstoß gegen ius cogens-Normen von allen Staaten zu verfolgen. Nach der Erörterung der betreffenden Konventionen, internationalen Abkommen und Fallentscheidungen des IGH, die diesen Grundsatz festschreiben, beschreibt er den - Friedensprozessen inhärenten - Konflikt, ein Gleichgewicht zwischen notwendiger Versöhnung und strafrechtlicher Verfolgung zu finden. Bei der Betrachtung des Fallrechts schließt Phenyo neuere Entscheidungen ein, wie die des britischen House of Lords im Fall Pinochet, die sowohl nationalen wie internationalen Gerichten das Recht auf Strafverfolgung internationaler Verbrechen zugestand. Stellvertretend für die weite Kritik der Generalamnestie des Lomé-Abkommens zitiert der Autor den VN-Generalsekretär Kofi Annan, der die Generalamnestie als unvereinbar mit der Tätigkeit und Aufgabe der internationalen Straftribunale in Den Haag und Arusha sowie des zukünftigen Internationalen Strafgerichtshofes ansieht. Phenyo schließt sich mit seiner kurzen Analyse des Friedensabkommens der kritischen Haltung Annans an und sieht nur eine geringe Möglichkeit für die Durchsetzung der fraglichen Amnestie, deren Gültigkeit durch die wiederaufgeflammten Kämpfe in Sierra Leone auch faktisch in Frage gestellt worden sind.

Humboldt's works on Mexico
(2000)
Humboldt wrote about Mexico from the perspective of a scientific explorer and naturalist. His works include his diaries, the Essai politique sur le royaume de la Nouvelle-Espagne, the Tablas géograficas, the Vues des Cordillères and a geographic atlas. Concerning the scientific aspect, the lack of a section on Mexico in the Relation historique is not a real deficit, since this can be found in the Essai. But only the diaries and letters from the journey, both published by the Alexander-von-Humboldt Research Centre, Berlin, can be considered an adequate substitute. The following will show the origin of Humboldt's writings on Mexico, offer historical and bibliographical facts and present the publications "Beiträge zur Alexander von Humboldt-Forschung", as well as Humboldt’s handwritten estate as far as they are available to us.
We continue the investigation of the calculus of Fourier Integral Operators (FIOs) in the class of symbols with exit behaviour (SG symbols). Here we analyse what happens when one restricts the choice of amplitude and phase functions to the subclass of the classical SG symbols. It turns out that the main composition theorem, obtained in the environment of general SG classes, has a "classical" counterpart. As an application, we study the Cauchy problem for classical hyperbolic operators of order (1, 1); for such operators we refine the known results about the analogous problem for general SG hyperbolic operators. The material contained here will be used in a forthcoming paper to obtain a Weyl formula for a class of operators defined on manifolds with cylindrical ends, improving the results obtained in [9].
We prove a general theorem on the behavior of the relative index under surgery for a wide class of Fredholm operators, including relative index theorems for elliptic operators due to Gromov-Lawson, Anghel, Teleman, Booß-Bavnbek-Wojciechowski, et al. as special cases. In conjunction with additional conditions (like symmetry conditions), this theorem permits one to compute the analytical index of a given operator. In particular, we obtain new index formulas for elliptic pseudodifferential operators and quantized canonical transformations on manifolds with conical singularities.
For a domain D subset of IRn with singular points on the boundary and a weight function ω infinitely differentiable away from the singularpoints in D, we consider a C*-algebra G (D; ω) of operators acting in the weighted space L² (D, ω). It is generated by the operators XD F-¹ σ F XD where σ is a homogeneous function. We show that the techniques of limit operators apply to define a symbol algebra for G (D; ω). When combined with the local principle, this leads to describing the Fredholm operators in G (D; ω).
The problem of analytic representation of integrable CR functions on hypersurfaces with singularities is treated. The nature o singularities does not matter while the set of singularities has surface measure zero. For simple singularities like cuspidal points, edges, corners, etc., also the behaviour of representing analytic functions near singular points is studied.
