Das Lehrbuch gibt eine systematische und kompakte Einführung in die mathematischen Grundlagen der Lie-Theorie mit dem Ziel, Symmetrien als eine der wesentlichsten Themen der modernen Physik zu verstehen. Beginnend mit einer Diskussion von Gruppen und deren linearen Darstellungen werden Lie-Gruppen und Lie-Algebren sowohl in abstrakter shape wie auch in Matrix-Form vorgestellt. Daran anschließend wird die Korrelation von linearen Matrix Lie-Gruppen mit einfacher zu handhabenden reellen Lie- Algebren behandelt, bei der die Matrix-Exponentialfunktion die Vermittlerrolle spielt. Die nachfolgende Einführung in die Strukturtheorie von komplexen und reellen halbeinfachen Lie-Agebren erlaubt eine Klassifizierung. Dabei werden Themen wie Cartan-Unteralgebren, Wurzelsysteme, Cartan- Matrizen und Weyl-Gruppen behandelt. Schließlich werden die für die Anwendung der Lie-Theorie wesentlichen Darstellungen halbeinfacher Lie-Algebren erörtert. Die Themen dort sind etwa Gewichte, Charaktere, Casimir-Operatoren, Tensorprodukte, Young-Tableaux und Unteralgebren. Die Darstellung verzichtet auf eine strenge mathematische äußere shape, um die Inhalte leichter zugänglich zu machen. 220 durchgerechnete Beispiele dienen der Vertiefung und erleichtern das Selbststudium.

'We discover largely within the valley of standard representations, and we take the reader over the mountain cross resulting in the valley of modular representations, to some degree from which (s)he can survey this valley, yet we don't try and broadly discover it. we are hoping the reader might be sufficiently occupied with the surroundings to additional discover either valleys on his/her personal' - from the Preface. illustration conception performs vital roles in geometry, algebra, research, and mathematical physics. specifically, it's been one of many nice instruments within the research and category of finite teams. the idea includes a few relatively appealing effects: Frobenius' theorem, Burnside's theorem, Artin's theorem, Brauer's theorem - all of that are lined during this textbook. a few appear uninspiring initially yet turn out to be particularly worthwhile. Others are essentially deep from the outset.And whilst a gaggle (finite or differently) acts on anything else (as a collection of symmetries, for example), one finally ends up with a traditional illustration of the crowd. This ebook is an advent to the illustration conception of finite teams from an algebraic standpoint, concerning representations as modules over the gang algebra. The method is to improve the needful algebra in moderate generality after which to specialize it to the case of workforce representations. tools and effects specific to team representations, akin to characters and precipitated representations, are constructed intensive. mathematics comes into play whilst contemplating the sphere of definition of a illustration, specifically for subfields of the complicated numbers.The booklet has an in depth improvement of the semisimple case, the place the attribute of the sphere is 0 or is key to the order of the crowd, and builds the principles of the modular case, the place the attribute of the sector divides the order of the crowd. The booklet assumes purely the cloth of a typical graduate path in algebra. it's compatible as a textual content for a year-long graduate direction. the topic is of curiosity to scholars of algebra, quantity thought and algebraic geometry. The systematic therapy awarded right here makes the e-book additionally invaluable as a reference.

A basic precept, came upon via Robert Langlands and named via him the ''functoriality principle'' predicts family members among automorphic kinds on mathematics subgroups of other reductive teams. Langlands functoriality relates the eigenvalues of Hecke operators performing on the automorphic types on teams (or the neighborhood elements of the ''automorphic representations'' generated by means of them). within the few situations the place such kinfolk were probed, they've got resulted in deep mathematics effects. This ebook reports one of many easiest basic difficulties within the idea, that of bearing on automorphic kinds on mathematics subgroups of GL (n, E) and GL (n, F) while E/F is a cyclic extension of quantity fields. (This is called the bottom switch challenge for GL (n) the matter is attacked and solved via the hint formulation. The ebook will depend on deep and technical effects received by means of a number of authors over the last two decades. it may now not function an advent to them, yet, by means of giving entire references to the printed literature, the authors have made the paintings helpful to a reader who doesn't be aware of the entire facets of the idea of automorphic varieties
