PeriodoSecondo semestre
LinguaItaliano
Students will learn and practice the theoretical and computational aspects in the area of approximation theory, orthogonal polynomials, numerical integration, and partial differential equations.
The student will be assessed on his/her demonstrated ability
- tto discuss the main course contents using the appropriate terminology
- to solve exercises
- to relate and compare different topics and techniques encountered in the course
- to report properties, theorems and their proofs
Methods:
- Final oral exam
- Final written exam
The student who successfully completes the course will have the ability to look at problems in approximation theory and in differential equations from the computational point of view. He/she will have the basic tools and the capabilities to learn more advanced tools and and algorithmic solutions. He/she will have the basis concepts needed for performing the design and analysis of algorithms and for approaching research topics.
The assessment criteria of skills rely on solving suitable exercises concerning different parts of the course.
Students will be able to read and analyze research results, design and analyze algorithms for solving numerical problems
Solving suitable and nonstandard exercises concerning different parts of the course are once again the main criteria for the assessment of behaviors.
Basic notions of linear algebra, functional analysis and numerical analysis.
