The course intends to give an introduction to, for example,
pseudodifferential operators and semiclassical analysis on manifolds, the
corresponding resolvents and heat kernels/complex powers/zeta functions,
spectral theory and related topics. It should be a good preparation for thesis work in real analysis or mathematical physics. Parts of it might also be of interest to
noncommutative geometers interested in quantizations and index theory.
Especially at the beginning we are going to rely on some hard theorems from DifFun2. You can find the proofs here.
