This biannual learning unit is being organized in 2022-2023
Teacher(s)
Ramos Gonzalez Julia;
Language
English
Prerequisites
Depending on the subject, mathematics skills at the level of the end of the Bachelor in Mathematics or first year Master in Mathematics.
Main themes
The topic considered varies from year to year depending on the research interests of the course instructor.
Learning outcomes

At the end of this learning unit, the student is able to :

1 Contribution of the course to learning outcomes in the Master in Mathematics programme. By the end of this activity, students will have made progress in: 
  • Show evidence of independent learning.
  • Analyse a mathematical problem and suggest appropriate tools for studying it in depth.
  • Begin a research project thanks to a deeper knowledge of one or more fields and their problematic issues in current mathematics. He will have made progress in:
    • Develop in an independent way his mathematical intuition by anticipating the expected results (formulating conjectures) and by verifying their consistency with already existing results.
    • Ask relevant and lucid questions on an advanced mathematical topic in an independent manner.
Learning outcomes specific to the course.
The course aims to initiate research in the field under consideration. Specific learning outcomes vary depending on the field.
 
Content
The course will provide an introduction to topos theory from a geometric perspective. The following topics will be covered during the course:
  • Presheaves and sheaves on topological spaces and locales
  • Localic topoi
  • Grothendieck topologies and sites
  • Presheaves and sheaves on a Grothendieck site
  • The sheafification functor
  • Grothendieck topoi and their properties
  • Characterization of Grothendieck topoi
  • Morphisms of sites and geometric morphisms
Teaching methods
The course will consist of lectures and exercise sessions. During the lectures the theoretical foundations of the subject will be provided, while the exercise sessions will permit students to work on examples and problems to assimilate and apply the material covered in the lectures.
Evaluation methods
The final mark consists of two parts:
  • continuous evaluation in the form of tasks/exercises/small projects (40%)
  • a written exam at the end of the quadrimester (60%)
The continuous evaluation will test the capacity of assimilating and applying the notions and results treated in the class. The written exam will test the knowledge and understanding of the main concepts and results of the theory.
Other information
It is recommended that the student is familiar with the basic concepts of category theory (LMAT2150 or a similar course).
