GEOMETRY II

Course objectives

General objectives: to acquire basic knowledge in general topology, with an introduction to algebraic topology and differential geometry. Specific objectives: Knowledge and understanding: At the end of the course the student will have acquired the concepts and the results basic general topology, with various possible approaches to the notions of topological space, continuous application, homeomorphism; then constructions of topologies on subspaces, products and quotients, topological properties of separation, numerability, compactness, and connection connection for arches. The student will also have acquired the notion of fundamental group and the its use together with the relevant calculation techniques, and the fundamental elements of the theory of topological coatings. Finally, the student will have acquired the basics of geometry differential of curves and surfaces in three-dimensional Euclidean space. Apply knowledge and understanding: At the end of the course the student will be able to solve simple topology problems, even with the use of elementary algebraic topology. He will also know use the notion of curvature in the contexts of the differential geometry of the curves and of the surfaces. Critical and judgmental skills: The student will have the basis for analyzing the similarities and relations between the topics covered and the fundamental notions of the theory of continuity and differentiability, also with tools that have historically led to the solution of classical problems. Communication skills: Ability to expose the contents in the oral part of the verification and in the any theoretical questions present in the written test. Learning ability: The acquired knowledge will allow a study, individual or given in a subsequent three-year or master's degree course, related to more advanced aspects of geometry.

Exam mode
The written exam will consist of exercises, possibly theoretical, aimed at assessing operational familiarity with the course topics. The oral exam will focus on the theoretical aspects of the subject. The minimum grade (18/30) corresponds to a non-in-depth understanding of all parts of the syllabus. The maximum grade (30/30, possibly with honors) corresponds to an excellent understanding of the topics, an excellent ability to discuss them, and more than good operational skills.
