# Global analysis

In mathematics, **global analysis**, also called **analysis on manifolds**, is the study of the global and topological properties of differential equations on manifolds and vector space bundles.^{[1]}^{[2]} Global analysis uses techniques in infinite-dimensional manifold theory and topological spaces of mappings to classify behaviors of differential equations, particularly nonlinear differential equations.^{[3]} These spaces can include singularities and hence catastrophe theory is a part of global analysis. Optimization problems, such as finding geodesics on Riemannian manifolds, can be solved using differential equations so that the calculus of variations overlaps with global analysis. Global analysis finds application in physics in the study of dynamical systems^{[4]} and topological quantum field theory.
