Bøger af Eckart Schmidt

This book, a translation of the German volume n-Ecke, presents an elegant geometric theory which, starting from quite elementary geometrical observations, exhibits an interesting connection between geometry and fundamental ideas of modern algebra in a form that is easily accessible to the student who lacks a sophisticated background in mathematics. It stimulates geometrical thought by applying the tools of linear algebra and the algebra of polynomials to a concrete geometrical situation to reveal some rather surprising insights into the geometry of n-gons. The twelve chapters treat n-gons, classes of n-gons, and mapping of the set of n-gons into itself. Exercises are included throughout, and two appendixes, by Henner Kinder and Eckart Schmidt, provide background material on lattices and cyclotomic polynomials.(Mathematical Expositions No. 18)

This unique atlas is the most comprehensive and up-to-date reference of laser scanning ophthalmoscopy. It correlates classical diagnostic tools such as perimetry, tonometry and fundus photography with state-of-the-art studies including digital retinal angiography, optical coherence tomography and laser scanning tomography.
