Description and Contextualization of the SubjectToggle Navigation
In this course, the algebraic structures of commutative ring, algebra and module are studied. The main properties of these structures will be studied, mainly concentrating in factorization properties. Thus, special importance will be given to unique factorization domains and, in particular, to rings of polynomials over a field. On the other hand, applications to different parts of algebra will be seen, especially in the case of modules over principal ideal domains.
This course, together with “Algebraic Structures” and “Algebraic Equations”, forms a module in which the fundamentals of abstract algebras and its main applications are developed. The student will obtain the basic techniques of this area, which can be used in other areas of mathematics, and, if they wish, they will be able to continue a deeper study of algebra via the optative fourth-year courses.

MethodologyToggle Navigation
The theoretical content will be exposed in theory classes following the basic references and the compulsory material appearing in the bibliography. These theory classes will be complemented by problem sessions, in which the students will be asked to solve problems to apply the knowledge obtained in the theory classes. In the seminars, relevant questions and examples will be discussed directly by the students through exercises, which will be assigned in advance. On the day of the seminar the proposed solutions will be discussed in a critical manner. Additionally, group problems will be proposed to improve teamwork. The solutions to these problems (both seminars and group problems) will be handed in, to be evaluated by the teacher.
An important part of the student's work is individual. Throughout the course, the teachers will guide this individual work and they will stimulate its regularity and the student's dedication. At the same time, the importance of personal tutoring session will be underlined.

Ordinary Call: Orientations and DisclaimerToggle Navigation
ORDINARY CALL
The final grade will be obtained via arithmetical mean of the following grades:
O1. Final written exam: 70%-100%
O2. Partial written exam: 0%-10%
O3. Individual problems and/or works (including seminars attendance): 0%-10%
O4. Group problems: 0%-10%
To pass the course, the minimum mark in the final written exam has to be greater than 4,5 out of 10.
The attendance to seminars of compulsory, unless properly justified by a proper supporting document.
In the case that sanitary conditions would obstruct the evaluation activities above specified, for all or part of enrolled students, the corresponding directives of the Rector will be followed.
Extraordinary Call: Orientations and DisclaimerToggle Navigation
EXTRAORDINARY CALL
Written exam of the extraordinary call: 100%
For the corresponding students, the totality of the grade will be determined by the written exam of the extraordinary call. Therefore, a mark of 5 in said exam will be necessary to pass the course.
In the case that sanitary conditions would obstruct the evaluation activities above specified, for all or part of enrolled students, the corresponding directives of the Rector will be followed.
