Credit Points
8 CP
1 semester
Methods Lecture 4 h + Exercise course 2 h
Objectives To have a firm command of the existence and regularity theories for solutions of nonlinear partial differential equations of second order.
Content - Hölder continuity of weak solutions of linear partial differential equations: Sobolev spaces, Harnack inequality, De Giorgi–Nash theory, Moser’s iteration technique. - Hölder continuity of the gradient of a solution: Application of the De Giorigi–Nash estimates to the gradient of the solution of an elliptic quasilinear differential equation, Morrey’s lemma. - Existence theory for quasilinear elliptic differential equations: Continuity method, fixed point theorems, Leray-Schauder’s fixed point theorem.
Learning outcomes The capability of solving problems in the underlying field. The capability to present the solutions in the exercise courses.
Suggested previous knowledge Partial Differential Equations I, Schauder theory.
Assessments Homework consisting of solving exercises and a written or oral examination at the end of the term.
