Geodesic and Horocyclic Trajectories (Universitext)

Prior to now thirty years, powerful relationships have interwoven the fields of dynamical platforms, linear algebra and quantity conception. This rapport among various components of arithmetic has enabled the solution of a few very important conjectures and has in truth given delivery to new ones. This ebook sheds gentle on those relationships and their purposes in an ordinary surroundings, via exhibiting that the learn of curves on a floor can result in orbits of a linear workforce or perhaps to persevered fraction expansions of actual numbers.

Least action principle of crystal formation of dense packing type and Kepler's conjecture

The dense packing of microscopic spheres (i. e. atoms) is the elemental geometric association in crystals of mono-atomic parts with vulnerable covalent bonds, which achieves the optimum "known density" of B/ 18. In 1611, Johannes Kepler had already "conjectured" that B/ 18 can be the optimum "density" of sphere packings.

Basic Concepts of Synthetic Differential Geometry

Beginning at an introductory point, the booklet leads swiftly to big and sometimes new ends up in artificial differential geometry. From rudimentary research the publication strikes to such vital effects as: a brand new evidence of De Rham's theorem; the substitute view of world motion, going so far as the Weil attribute homomorphism; the systematic account of established Lie gadgets, resembling Riemannian, symplectic, or Poisson Lie items; the view of worldwide Lie algebras as Lie algebras of a Lie workforce within the artificial feel; and finally the artificial development of symplectic constitution at the cotangent package deal normally.

Coulomb Frames in the Normal Bundle of Surfaces in Euclidean Spaces: Topics from Differential Geometry and Geometric Analysis of Surfaces

This ebook is meant for complicated scholars and younger researchers drawn to the research of partial differential equations and differential geometry. It discusses hassle-free options of floor geometry in higher-dimensional Euclidean areas, particularly the differential equations of Gauss-Weingarten including numerous integrability stipulations and corresponding floor curvatures.
