## Textbook

- L. Evans,
*Partial Differential Equations*(2nd edition) - Additional: H. Brézis,
*Functional Analysis, Sobolev Spaces and Partial Differential Equations*

### Course description

This course introduces rigorous methods to study partial differential equations such as existence theory and global behavior of solutions. The goal is to understand *intuitively* PDEs and then to develop analytic skills to * prove* results. This class is intended to be spread over two semesters, the first semester will be focused on **linear PDEs** (e.g. elliptic, parabolic equations) and the second semester on **non-linear PDEs** (e.g. conservation laws, Hamilton-Jacobi equations).

The course will be divided in four parts:

- a) Review PDEs
*(Chap. 1, Chap. 2.1-2.3)* - b) Functional analysis
*(Chap. 5.2-5.7)* - c) Elliptic PDEs
*(Chap. 6)* - d) Evolution equations
*(Chap. 7)*
