A relevant application of nonlinear functional analysis and calculus of variations can be found
here.
Rough list of topics to be covered in approximate chronological order:
- L_p spaces
- Normed vector spaces, Banach spaces
- Space of continuous functions
- Point-set topology in infinite-dimensional spaces (open, closed, compact, etc.)
- Subspaces, some notions of basis
- Bounded linear operators and functionals
- Dual/conjugate spaces
- Reisz representation theorems
- Inner-product spaces, Hilbert spaces, some notions of basis
- Hahn-Banach Theorem
- Nonlinear functions, Gateaux and Frechet derivatives
- Sobolev spaces
- Calculus of Variations
- Closed operators, closed graph theorem
- Integral equations, Fredholm operators
- Spectral analysis, approximation
IF we decide to make a side quest into stochastic processes, some of the above topics would be replaced with the following.
- Brownian motion and Wiener measure
- Ito integrals
- Stochastic differential equations and notions of solution
- Girsanov transform
- Feynman-Kac and Fokker-Planck
