Prerequisites:

Differential and integral calculus.
Elementary theory of ordinary differential equations.
Basic theory of complex analysis (functions of complex variables, holomorphic and analytic functions). 
Target skills and knowledge:

Basic notions of the theory of linear partial differential equations. It's a fundamental course suggested to students with interests both in pure and in applied mathematics, and in particular to students with a curriculum in analysis. 
Examination methods:

The exam consists of a final oral examination on the topics treated in class. There will be both theoretical questions and the discussion of some exercise to solve. 
Assessment criteria:

The evaluation criteria will be the following:
 coherence and rigor in the exposure of statements and theorems
 thoroughness and adherence to the topics of discussion
 ability to use the acquired knowledge to solve problems and exercises. 
Course unit contents:

Didactic plan:
 First order PDEs: transport equation with constant coefficients, conservation laws (classical and weak solutions, RankineHugoniot conditions, Riemann problem).
 Wave equation: existence of solutions, D'alembert formnula, method of spherical means, Duhamel's principle, uniqueness, finite speed of propagation.
 Laplace equation: fundamental solution, harmonic functions and main properties, mean value formulas, Harnack's inequality, maximum principle. Poisson equation. Green's function and Poisson's representation formula of solutions.
 Heat equation: fundamental solution, existence of solutions for the Cauchy problem and representation formula. Uniqueness and stability of solutions. Mean value formulas, maximum principle, Hopf's maximum principle. 
Planned learning activities and teaching methods:

The methodology of teaching used will be the traditional lesson.
