# 58: Global analysis, analysis on manifolds

## Introduction

Global analysis, or analysis on manifolds, studies the global nature of differential equations on manifolds. In addition to local tools from ordinary differential equation theory, global techniques include the use of topological spaces of mappings. In this heading also we find general papers on manifold theory, including infinite-dimensional manifolds and manifolds with singularities (hence catastrophe theory), as well as optimization problems (thus overlapping the Calculus of Variations.

(The real introduction to this area will have to summarize the Atiyah-Singer Index Theorem!)

## Applications and related fields
