Non-Euclidean Laguerre Geometry and Incircular Nets (eBook, PDF)

• Format: PDF

Produktbeschreibung

This textbook is a comprehensive and yet accessible introduction to non-Euclidean Laguerre geometry, for which there exists no previous systematic presentation in the literature. Moreover, we present new results by demonstrating all essential features of Laguerre geometry on the example of checkerboard incircular nets.
Classical (Euclidean) Laguerre geometry studies oriented hyperplanes, oriented hyperspheres, and their oriented contact in Euclidean space. We describe how this can be generalized to arbitrary Cayley-Klein spaces, in particular hyperbolic and elliptic space, and study the corresponding groups of Laguerre transformations. We give an introduction to Lie geometry and describe how these Laguerre geometries can be obtained as subgeometries. As an application of two-dimensional Lie and Laguerre geometry we study the properties of checkerboard incircular nets.

Rezensionen

"In this short book the authors present non-Euclidean Laguerre geometry, related Möbius and Lie geometries, and their transformations, and demonstrate how these geometries can be applied to the study of checkerboard incircular nets. ... Two appendices summarize defnitions and properties of Euclidean Laguerre geometry and generalized signed inversive distance. Throughout the text, many instructive diagrams aid the visualization of the concepts and constructions." (Günter F. Steinke, Mathematical Reviews, Issue 2, March, 2024)

"The book is very geometric in flavour and contains lots of instructive illustrations." (Norbert Knarr, zbMATH 1492.51001, 2022)
