This ebook grew out of lectures offered to scholars of arithmetic, physics, and mechanics by way of A. T. Fomenko at Moscow college, below the auspices of the Moscow Mathematical Society. The ebook describes smooth and visible points of the speculation of minimum, two-dimensional surfaces in three-d house. the most subject matters coated are: topological homes of minimum surfaces, good and volatile minimum motion pictures, classical examples, the Morse-Smale index of minimum two-surfaces in Euclidean house, and minimum motion pictures in Lobachevskian house. Requiring just a commonplace first-year calculus and simple notions of geometry, this e-book brings the reader quickly into this attention-grabbing department of contemporary geometry.

Fibre bundles, now an essential component of differential geometry, also are of significant value in smooth physics - corresponding to in gauge concept. This publication, a succinct advent to the topic by way of renown mathematician Norman Steenrod, was once the 1st to offer the topic systematically. It starts with a normal creation to bundles, together with such issues as differentiable manifolds and protecting areas.

The purpose of those lecture notes is to offer an primarily self-contained creation to the fundamental regularity thought for strength minimizing maps, together with contemporary advancements about the constitution of the singular set and asymptotics on method of the singular set. really good wisdom in partial differential equations or the geometric calculus of diversifications is no longer required.

Then F decomposes into two components. iIltersections points 8H with the rays starting from the inner points of H and having the opposite direction from the ray L+. ut, 18 Chapter 1. Convex Bodies and Hypersurfaces Thus every point A E [)H has a neighborhood U C [)H, which is projected one-to-one in a hyperplane. Let W(G) be the set of convex hypersurfaces in En+l which project orthogonally and one-to-one onto a convex open domain G C P. Let Xl, ... , X n, X n+ 1 = z be Cartesian coordinates in En+!
Moreover, the point Ak (k = 1, 2, ... , m) is a vertex of P if and only if Ak does not belong to CO(AI U ... U A k - l U Ak+l U ... U Am U V). 6 can be an (n + 1)-convex polyhedral angle. The last theorem has a natural generalization if V is any k-convex solid polyhedral angle in En+l. The proof of this generalization will be left as a useful exercise. 3 Approximation of Closed Convex Hypersurfaces by Closed Convex Polyhedra Let S be any closed convex hypersurface in En+l. Denote by F the bounded solid convex body such that S = BF.
The proof of this generalization will be left as a useful exercise. 3 Approximation of Closed Convex Hypersurfaces by Closed Convex Polyhedra Let S be any closed convex hypersurface in En+l. Denote by F the bounded solid convex body such that S = BF. Remember that closed n-convex polyhedra are considered as closed convex hypersurfaces in En+l. The closed nconvex polyhedron P is said to be inscribed in the closed hypersurface S if all its vertices belong to S. 7. There exists a sequence of closed n-convex polyhedra inscribed in any convex hypersurface S which converges to S.
