Sommario/riassunto |
|
What is a mathematical proof? How can proofs be justified? Are there limitations to provability? To what extent can machines carry out mathe matical proofs? Only in this century has there been success in obtaining substantial and satisfactory answers. The present book contains a systematic discussion of these results. The investigations are centered around first-order logic. Our first goal is Godel's completeness theorem, which shows that the con sequence relation coincides with formal provability: By means of a calcu lus consisting of simple formal inference rules, one can obtain all conse quences of a given axiom system (and in particular, imitate all mathemat ical proofs). A short digression into model theory will help us to analyze the |

expres sive power of the first-order language, and it will turn out that there are certain deficiencies. For example, the first-order language does not allow the formulation of an adequate axiom system for arithmetic or analysis. On the other hand, this difficulty can be overcome--even in the framework of first-order logic-by developing mathematics in set-theoretic terms. We explain the prerequisites from set theory necessary for this purpose and then treat the subtle relation between logic and set theory in a thorough manner. |

Sommario/riassunto |
|
Civil wars pose some of the most difficult problems in the world today and the United Nations is the organization generally called upon to bring and sustain peace. Lise Morjé Howard studies the sources of success and failure in UN peacekeeping. Her in-depth 2007 analysis of some of the most complex UN peacekeeping missions debunks the conventional wisdom that they habitually fail, showing that the UN record actually includes a number of important, though understudied, success stories. Using systematic comparative analysis, Howard argues that UN peacekeeping succeeds when field missions establish significant autonomy from UN headquarters, allowing civilian and military staff to adjust to the post-civil war environment. In contrast, failure frequently results from operational directives originating in UN headquarters, often devised in relation to higher-level political disputes with little relevance to the civil war in question. Howard recommends future reforms be oriented toward devolving decision-making power to the field missions. |
