 body { font-size: 9pt; font-family: Arial } table { font-size: 9pt; font-family: Arial } The first two weeks of the study unit “Algorithmic Discrete Mathematics” are devoted to the understanding of elementary data structures, and their use in the design and theoretical analysis of classic discrete algorithms. This includes basic principles and techniques to analyse the time and space complexity of algorithms, worst-case and average-case. The data structures include heaps, binary trees, as well as priority queues. Algorithms that are dealt with are for sorting, computational problems with permutations, the Euclidean algorithm to compute the greatest common divisor, the computation of shortest paths, minimum spanning trees. General algorithmic techniques that are introduced are divide and conquer, as well as dynamic programming. Some of these algorithms are implemented using the Python programming language, as part of the graph isomorphism implementation project. The third and fourth weeks are devoted to structural, algorithmic, and combinatorial problems that lie in the core of discrete and combinatorial mathematics: Students understand core algorithmic techniques in discrete optimization, next to shortest paths and spanning trees also algorithms for network flows, stable matchings and clustering, the algorithmic power of duality on the example of maximum flows and minimum cuts, and learn how to solve combinatorial counting problems by means of (second-order, linear) recurrence relations using the characteristic polynomial. The "Algebra" part of the course provides an introduction to abstract algebra and some of its applications. Three families of algebraic structures are introduced and studied: groups, rings and fields. Roughly speaking groups are generalisations of the set of integers equipped with addition. Rings are generalisations of the set of integers equipped with both addition and multiplication. Fields are generalisations of the set of rational numbers equipped with addition, multiplication and division by nonzero numbers. The generalisations go as far as finite structures and structures in which the operation(s) are non-commutative. The backbones of the course are constructions for groups and the understanding of structure-preserving maps. As to applications of algebraic structures, the course addresses encryption based on RSA, the word problem, symmetries and isomorphisms in adjacent mathematical domains, topological data analysis, and homotopy type theory. The learning and understanding of abstract algebraic structures will be supported by mandatory Grasple exercises. Topics covered in this course are: Constructions of groups: Integers and integers modulo n, matrix groups, symmetry groups and groups of functions Group Theory: group operations, cosets & Lagrange Theorem, group homomorphism, crucial structures in groups Rings and Fields Applications of Algebra including encryption, data analysis and the recognition of structure-preserving transformations  Assumed previous knowledge Linear maps between vector spaces; calculations with matrices; properties of real and complex numbers; working with functions and relations Participating study Bachelor Applied Mathematics     Participating study Bachelor Applied Physics  Required materials
