# Programme of Course "Matematica Discreta I"

FN

### Type of course unit:

Bachelor Degree in Computer Science curriculum General: Compulsory

2nd semester

### Number of credits:

Bachelor Degree in Computer Science: 6 (workload 150 hours)

## 1. Course Objectives

The goal of this course is to expose the main concrete techniques in linear algebra (matrices, systems, determinants, vector spaces and linear maps) and to show the first strategies in abstract algebra.

## 2. Course Contents and learning outcomes (Dublin Descriptors)

Topics of the course include:

• Sets: functions, equivalence relations, products, elementary combinatorics.
• Permutations.
• Groups: subgroups, quotients, isomporphism theorems, factor groups, permutation groups, cyclic groups.
• Arithmetic: divisibility theory in the ring of integers and of polinomials over a field.
• Congruences. Chinese remainder theorem.
• Rings: subrings, ideals, quotients, isomorphism theorem, ring of polynomials, domains, euclidean rings, PID, UFD.
• Fields: simple field extensions, finite fields.
• Matrices and systems of linear equations: Gauss reduction, determinants.
• Vectors, vector spaces, independence, bases.
• inner product, cross product.
• Eigenvalues, eigenvectors. Diagonalization and canonical forms of matrices.
• Application: systems of differential equations.

On successful completion of this course, the student should

• being aware of the main structures in Linear Algebra and Abstract Algebra.

• demonstrate skill in mathematical reasoning, manipulation and calculation, demonstrate capacity for finding rigorous proofs of small problems; demonstrate skill in mathematical reasoning, manipulation and calculation by synthesizing geometric concepts into algebraic, functional, and problem-solving activities; demonstrate capacity to deduce properties of, and relationships between, figures from given assumptions and from using transformations.

## 3. Course Prerequisites
