Global analysis provides essential theoretical foundations for advanced studies in differential geometry, partial differential equations, and theoretical physics. The theory of manifolds and differential forms offers a coordinate-free framework for formulating and analyzing geometric and analytical problems on curved spaces. The course introduces key concepts such as tangent/vector bundles, differential forms, the exterior derivative, integration on manifolds, and Stokes' theorem, enabling the formulation of global properties of solutions to differential equations and field theories. An important tool in this endeavour will be the powerful techniques of pseudodifferential operators that allow us to understand the geometric analysis of manifolds. These tools are indispensable in modern applications and of importance to students aiming to specialize in pure or applied mathematics with a geometric focus.

In this course we will study the geometry of manifolds by means of the differential operators thereon and their analytic properties. The course will focus on the view towards global results starting from a local perspective. The course introduces key geometric concepts such as tangent/vector bundles, differential forms, the exterior derivative, integration on manifolds, and Stokes' theorem. The course will also introduce the machinery of pseudodifferential operators as a method to study the elliptic differential operators arising on manifolds. The highlights from this include the de Rham theorem relating the exterior derivative to cohomology.
