# Computational Algebra

Academic Year 2023/2024 - Teacher: VINCENZO MICALE

## Expected Learning Outcomes

Computational Algebra - 6 CFU - 47 total hours

33 frontal lessons

14 exercises.

The objective of the second module of the course is to introduce the theory of Groebner bases , in order to begin the computational student to algebra and its applications

## Course Structure

Teaching is done on the blackboard in a traditional way. The exercises also include using the computer. If the teaching is given in mixed or remote mode, they can be introduced the necessary changes with respect to what was previously stated, in order to comply the planned program and reported in the syllabus.

Information for students with disabilities and / or SLD. To guarantee equal opportunities
and in compliance with the laws in force, interested students can ask for a personal interview
in order to plan any compensatory and / or dispensatory measures, based on the didactic objectives
and specific needs. It is also possible to contact the referent teacher CInAP (Center for Active
and Participated Integration - Services for Disabilities and / or SLD) of our Department,
prof. Filippo Stanco.

## Learning Assessment

### Learning Assessment Procedures

Practical exercises will be assigned to be solved on the computer using software;
if solved with at least a sufficient score, you will move on to an oral exam.
The results of the exercises carried out during the course will not be taken into account.
Verification of learning can also be carried out electronically, should conditions require it.

### Examples of frequently asked questions and / or exercises

Characterization theorem of Groebner bases. Applications of Groebner Bases to Algebra and Algebraic
Geometry. Calculation of the modulus of the syzygies of an ideal.
