By Gerd Fischer

Dieser Band (eine Ergänzung zum Lehrbuch Lineare Algebra des Autors) enthält Anwendungen der linearen Algebra auf geometrische Fragen. Ausgehend von affinen Unterräumen in Vektorräumen werden allgemeine affine Räume eingeführt, und es wird gezeigt, wie sich geometrische Probleme mit algebraischen Hilfsmitteln behandeln lassen. Ein Kapitel über lineare Optimierung befasst sich mit Systemen linearer Ungleichungen. Mit Hilfe der elementaren Theorie konvexer Mengen kann guy die Optimierung eines linearen Funktionals auf die Lösung linearer Gleichungssysteme zurückführen. Anschließend wird der für praktische Anwendungen so wichtige Simplex-Algorithmus abgeleitet. Besonderer Wert wird dabei auf einen Einblick in die geometrischen Zusammenhänge gelegt.

Download E-books Geometry of Hypersurfaces PDF

By Thomas E. Cecil

This exposition presents the state-of-the artwork at the differential geometry of hypersurfaces in genuine, complicated, and quaternionic area varieties. unique emphasis is put on isoparametric and Dupin hypersurfaces in actual house kinds in addition to Hopf hypersurfaces in advanced house varieties. The publication is on the market to a reader who has accomplished a one-year graduate path in differential geometry. The textual content, together with open difficulties and an in depth record of references, is a wonderful source for researchers during this area.

Geometry of Hypersurfaces starts off with the fundamental concept of submanifolds in genuine house types. subject matters contain form operators, primary curvatures and foliations, tubes and parallel hypersurfaces, curvature spheres and focal submanifolds. the focal point then turns to the idea of isoparametric hypersurfaces in spheres. vital examples and category effects are given, together with the development of isoparametric hypersurfaces in line with representations of Clifford algebras. An in-depth therapy of Dupin hypersurfaces follows with effects which are proved within the context of Lie sphere geometry in addition to those who are got utilizing ordinary equipment of submanifold conception. subsequent comes an intensive remedy of the idea of genuine hypersurfaces in advanced house forms.  A valuable concentration is a whole facts of the type of Hopf hypersurfaces with consistent imperative curvatures as a result of Kimura and Berndt. The e-book concludes with the elemental concept of genuine hypersurfaces in quaternionic area kinds, together with statements of the most important type effects and instructions for extra research.

Download E-books Rings and Geometry PDF

By P. M. Cohn (auth.), Rüstem Kaya, Peter Plaumann, Karl Strambach (eds.)

When trying to find purposes of ring concept in geometry, one first thinks of algebraic geometry, which occasionally will even be interpreted because the concrete facet of commutative algebra. despite the fact that, this hugely de­ veloped department of arithmetic has been handled in numerous mono­ graphs, in order that - regardless of its technical complexity - it may be considered as particularly good available. whereas within the final a hundred and twenty years algebraic geometry has time and again attracted centred interes- which instantaneously has reached a height once again - , the various different purposes of ring idea in geometry haven't been assembled in a textbook and are scattered in lots of papers in the course of the literature, which makes it demanding for them to emerge from the shadow of the intense thought of algebraic geometry. it's the objective of those complaints to offer a unifying presentation of these geometrical functions of ring theo~y outdoors of algebraic geometry, and to teach that they provide a substantial wealth of beauti­ ful rules, too. additionally it turns into obvious that there are ordinary connections to many branches of contemporary arithmetic, e. g. to the idea of (algebraic) teams and of Jordan algebras, and to combinatorics. To make those feedback extra distinctive, we are going to now supply an outline of the contents. within the first bankruptcy, an method in the direction of a thought of non-commutative algebraic geometry is tried from various issues of view.
