Learning Outcomes

Learning outcomes Algebraic topology is a twentieth century field of mathematics that can trace its origins and connections back to the ancient beginnings of mathematics. One of the strengths of algebraic topology has always been its wide degree of applicability to other fields. Nowadays that includes fields like physics, differential geometry, algebraic geometry, and number theory, biology, financial sciences, computer sciences. We expect familiarity with basic notions from point set topology. We study the compact open topology and function spaces as an introduction to homotopy between maps. The main Learning Outcomes can be described as the application of Cell complexes and the category of CW spaces in connection between homotopy-homology and important problems in geometry. Moreover, how do we compute using homotopy? How can we distinguish between topological spaces? We compute the fundamental groups of basic topological spaces and classify covering spaces. Singular homology is introduced along with the main technics of computations. Search for analysis and synthesis of data and information related with topological and geometrical problems. Working independently and in a Team work. Working in an interdisciplinary environment aiming at production of new research ideas related to the syllabus of the course.
