Math 555 Spring 2016

Nonlinear Analysis and Partial Differential Equations



Room: 441 Altgeld

Time: TTh 11:00 am - 12:20 pm

Lecturer: Eduard-Wilhelm Kirr

Syllabus:

  1. Implicit and inverse function theorem in Banach spaces. Application to existence, uniqueness and bifurcation of solutions of nonlinear elliptic PDE's. Basic theory is in Section 2.7 of L. Nirenberg: ``Topics in Nonlinear Functional Analysis", the application will be taken mostly from recent papers dealing with models in optics, statistical physics and molecular chemistry.
  2. Calculus of Variations concentration compactness and applications to existence, uniqueness and stability of solutions of nonlinear PDE's. Basic theory of calculus of variations is in L.C. Evans "Partial Differential Equations", concentration compactness is in T. Cazenave: ``Semilinear Schroedinger Equations" the applications will come from the second book and papers.
  3. Semigroups of operators. Applications to existence, uniqueness and stability of solutions of nonlinear evolution PDE's. Basic theory is in L.C. Evans "Partial Differential Equations" or A. Pazy: ``Semigroups of linear operators and applications to partial differential equations". Applications will be mainly from the latter and recent papers.

Prerequisites: Real analysis (Math 447 or equivalent) and multivariable calculus. Familiarity with theory of linear operators and with partial differential equations (Math 553 or 554) would be helpful.
