#### Objectives

Numerical and theoretical study of the finite element method and its application

#### Teaching methods

Lessons and computer lab practice

#### Examination

Oral examination.

#### Prerequisites

Fundamental notions of Analysis and Numerical Analysis

#### Syllabus

Theory lessons will cover the following topics:
- fundamentals of Functional Analysis, with a particular emphasis on the W^{k,p} spaces and on primal variational formulations of elliptic problems
- approximation theory in Sobolev spaces: Deny-Lions Lemma and Brambe-Hilbert lemma
- Lagrange interpolation on n-simplices and corresponding interpolation error for Sobolev norms
- Galerkin method for elliptic problems and error estimates: Cea Lemma and duality techniques
- finite element methods for elliptic problems, with particular emphasis to the bidimensional case
- mixed formulation of elliptic problems and its Galerkin
discretization: existence, uniqueness, stability of the solution, and
error analysis.
- mixed finite elements for the Laplacian in mixed form (Darcy)
- finite elements for the Stokes system

Computer lab lessons will address the implementation of the finite
element method, in MATLAB language. In particular some of the following:
- data structure and algorithm for the triangulation of a planar region
- interpolation and numerical integration of funtions on the triangulation
- local matrices and assembling
- Dirichlet and Neumann boundary condition
- finite element method for the Poisson problem in primal form with P1 elements
- implementation of the RT element
- finite element method for the Poisson problem in mixed form (Darcy problem)

REMARK: This is a tentative program. Significant changes might occur,
also depending on the feedback provided by the Student during the
Lectures.
