### Vorlesung: Viscosity Solutions for nonlinear PDEs 2 (SoSe 2015)

Content of the lecture

Time, room (Zeit und Ort): Tuesday 16-18Uhr in A 027 (First meeting: April 14).

Exercises (Übungen): There are NO exercises!

Synopsis (Kurzbeschreibung): This course is a continuation of my lecture 'Viscosity Solutions for nonlinear PDEs' in the past semester (WiSe 2014/15). It treats the regularity theory of viscosity solutions for linear and nonlinear PDEs (whereas the first course treated the definition, uniqueness (Comparison Principles), and existence (Perron's Method) of viscosity solutions).
Keywords: Viscosity solutions, fully nonlinear elliptic PDEs, Alexandroff estimate and maximum principle (ABP estimate), Harnack inequality, W^{2,p}-regularity, Hölder regularity, Gradient Hölder regularity.

Audience (Hörerkreis): Master students of Mathematics (WP 17.2, 18.1, 18.2, 44.3, 45.2, 45.3), TMP-Master.

Credits: 3 ECTS.

Exam (Prüfung): There will be an oral exam of 30min (Es wird eine mündliche Prüfung von 30min geben).

Prerequisites (Vorkenntnisse): This course is a continuation of 'Viscosity Solutions for nonlinear PDEs' (WiSe 2014/15). Students who wish to follow this course, but did not follow the course last semester, should (in due time!) contact the Lecturer (Prof. Sørensen) via email to discuss the prerequisites needed.

Language (Sprache): English. (Die mündliche Prüfung kan auch auf Deutsch gemacht werden).

Literature: There will be no lecture notes. Here you will find a short description of the content of the lecture (to be updated as we go along). The lecture will mainly follow the book by Caffarelli and Cabré mentioned below. (Es wird kein Skript geben. Hier wird laufend eine Kurzübersicht der Vorlesung erstellt. Die Vorlesung wird größtenteils auf folgendes Buch basieren:)

[CC] L. A. Caffarelli, X. Cabré, Fully Nonlinear Elliptic Equations, AMS (Colloquium Publications), 1995.
