For background on manifolds and smooth maps, I suggest Guillemin/Pollack (Differerntial Topology, Chapter 1), or Lee (Riemannian Manifolds)
For a resource on PDE with Euclidean domains, I suggest Evans (Partial Differential Equations)
For more about elliptic theory, a good resource is Roe (Elliptic Operators, Topology, and Asymptotic Methods)
Some suggested topics for the paper and/or presentation, and some guidelines
