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–Kähler about the analytical solutions to an analytical exterior differential system.

Physikalisch-chemische Natur der Schlacken,alisation of the notion of a 3-Sasakian manifold. 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.
