OVERVIEW
Algebra 1 presents the basic mathematical language and a first introduction to algebraic structures. This is done through the preliminary analysis of the algebraic structures of the set of integers and of the set of polynomials with coefficients in a field, of their quotients and through the study of the first properties of abstract groups.
AIMS AND CONTENT
LEARNING OUTCOMES
The aim of this course is to provide students with basic mathematical language, to introduce them to more abstract algebraic notions by first studying properties of the integers, of univariate polynomials with coefficeints in rational, real, complex numbers or in finite fields, and of quotients of polynomial rings, to introduce them to basic aspects of group theory.
AIMS AND LEARNING OUTCOMES
Algebra 1 aims to provide the basics of:
1) mathematical language and formalization.
2) concrete algebraic structures. In particular those derived from integers and from the set of polynomials.
3) abstract algebraic structures. In particular, integer and polynomial quotients and basic notions of group theory.
The expected learning outcomes are:
1) At the end of Algebra 1 one is able to understand and write sentences using formal mathematical language.
2) At the end of Algebra 1 one is able to solve exercises related to applications between sets, equivalence relations, cardinality.
3) At the end of Algebra 1 one is able to compare and classify concrete algebraic structures arising from integers and polynomials.
4) At the end of Algebra 1 one is able to answer questions about the structure of an abstract group and its quotients,
5) At the end of Algebra 1 one is able to reproduce, analyze and generalize the main proofs presented.
