| Описание: | The purpose of these notes is to illustrate some techniques in modern finite group theory by describing their application in particular cases. These applications are to characterisations of simple groups which, for the most part, are odd in two senses of the word: They are characterisations of individual groups rather than whole classes, and they are characterisations in terms of properties of subgroups of odd order. I believe them to be rather suitable for beginners to cut their teeth on, because they are neither so trivial that the principles are not illustrated nor so complicated that the fog of detail obscures everything. However, the choice does mean that a number of topics important for the theory of finite simple groups are omitted (for instance, modular characters). |
