Competencies / intended learning achievements

Upon successful completion of this module, the students have studied and understand the basic methods and statements of homology and cohomology of groups. They have learnt important examples and are able to investigate them by using scientific methods. They are able to name the essential propositions of the lecture as well as to classify and to explain the connections. They understand the proofs presented in the lecture and are able to comprehend and explain them. In particular, they are able to outline the conditions and assumptions that are necessary for the validity of the statements.

By completing exercises, the students have developed a skilled, precise and independent handling of the terms, propositions and techniques taught in the lecture.
