On the Hopf Conjecture with Symmetry,r the assumption that a torus of sufficiently large dimension acts by isometries. This improves previous results by replacing linear bounds by a logarithmic bound. The new method that is introduced is the use of Steenrod squares combined with geometric arguments of a similar type to what was done be

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. Moreover we discuss the algebraic properties of the Spencer cohomology associated to an exterior differential system and ske

Riemannian Manifolds with Positive Sectional Curvature,Of special interest in the history of Riemannian geometry have been manifolds with positive sectional curvature. In these notes we give a survey of this subject and recent developments.
