MA8105 Nonlinear Partial Differential Equations and Sobolev Spaces
Spring 2019
Welcome to MA8105 !
- What is this course about?
- Mathematical methods and structures that are fundamental for the study of partial differential equations (PDEs), variational calculus, numerical methods etc.
- Main focus on analytical tools: Functional analysis, \(L^p\) and Sobolov spaces, compactness, modes of convergence, distributions, error estimates.
- 1-3 weeks on applications to linear and nonlinear PDEs.
- Who can take this course?
- Interested students at Master or PhD level.
- The level should be suitable for good 4th year students in the industrial mathematics program.
- It can be taken as a regular course or a 'fordypningsemne'.
- Very relevant for students specialising in PDEs, optimization, analysis, numerical analysis, or probability.
- Prerequisites:
- Elementary functional analysis, equivalent to TMA4145 Linear Methods.
- Some real analysis (Lebesgue integration theory).
- It is advantageous, but not necessary, to have some background in partial differential equations.
