This improves previous results by replacing linear bounds by a logarithmic bound.

An Introduction to Exterior Differential Systems, this introduction we construct the contact systems on several kinds of jet bundles in order to reduce general partial differential equations to exterior differential systems.

An Introduction to Exterior Differential Systems,ior differential systems. Moreover we discuss the algebraic properties of the Spencer cohomology associated to an exterior differential system and sketch a proof of the theorem of Cartan–K?hler about the analytical solutions to an analytical exterior differential system.作者: 談判 時(shí)間: 2025-3-26 12:27

The examples discussed are related to the theory of isoparametric hypersurfaces of spheres with four principal curvatures. These examples carry Einstein metrics and in some special cases carry metrics with positive sectional curvature.作者: Conspiracy 時(shí)間: 2025-3-26 13:37
