Seminare Dieses Semester haben viele Seminare eine Warteliste mit speziellem Auswahlverfahren. Falls keine anderen Auswahlkriterien vorliegen, werden bei der definitiven Belegung zuerst jene Studierenden berücksichtigt, welche noch keine andere Seminarbelegung haben. Wenn Sie sich in zwei Wartelisten eintragen, so tun Sie dies am besten so: wählen Sie zuerst das Seminar aus, das Sie bevorzugen, und wählen Sie anschliessend eine Ausweichmöglichkeit aus.
401-3180-20L	Introduction to Homotopy Theory and Model Category Structure Number of participants limited to 24.	W	4 KP	2S	J. Ducoulombier
Kurzbeschreibung	Introductory seminar about category theory and techniques in Algebraic topology such as model category structure and "homotopy" limits and colimits.
Lernziel	It is well known that topological spaces are endowed with a homotopy theory classifying objects up to continuous deformations. Model categories provide a natural setting for homotopy theory and it has been used in some parts of algebraic K-theory, algebraic geometry and algebraic topology, where homotopy-theoretic approaches led to deep results. The goal of this seminar is to get an introduction to model structures through examples (topological spaces, simplicial sets, chains complexes...). To get further into this theory, we develop the notion of derived functors with applications to homotopy limits and colimits.
Literatur	"Homotopy theories and model categories" Dwyer and Spalinski "A primer on homotopy colimits" Dugger "Model categories" Hovey
Voraussetzungen / Besonderes	The students are expected to be familiar with topological spaces and fundamental groups. This seminar takes the form of a working group, where interactions are encouraged. Participants are expected to attend the seminar, give a presentation and write a report. Topic will be assigned during the first meeting.
401-3200-69L	A Survey of Geometric Group Theory Number of participants limited to 24.	W	4 KP	2S	M. Cordes
Kurzbeschreibung	In this class we will cover some of the tools, techniques, and groups central to the study of geometric group theory. After introducing the basic concepts (groups and metric spaces), we will branch out and sample different topics in geometric group theory based on the interest of the participants.
Lernziel	To learn and understand a wide range of tools and groups central to the field of geometric group theory.
Inhalt	Possible topics include: properties of free groups and groups acting on trees, large scale geometric invariants (Dehn functions, hyperbolicity, ends of groups, asymptotic dimension, growth of groups), and examples of notable and interesting groups (Coxeter groups, right-angled Artin groups, lamplighter groups, Thompson's group, mapping class groups, and braid groups).
Literatur	The topics will be chosen from "Office Hours with a Geometric Group Theorist" edited by Matt Clay and Dan Margalit.
Voraussetzungen / Besonderes	One should be familiar with the basics of groups, metric spaces, and topology (should be familiar with the fundamental group).

401-3200-16L	Power Sums of Coxeter Exponents (With Some Insight Into the Evolution of an Article) Number of participants limited to 12.	W	4 KP	2S	R. Suter
Kurzbeschreibung	In addition to its mathematical content, this seminar shall provide an insight into what is usually hidden away from the reader of an article.
Lernziel	The gradual development from an initial wish to make progress on a certain topic towards a published article is usually hidden away in the final text. The idea of this seminar is to have a look at the two author paper "Power sums of Coxeter exponents" (Advances in Mathematics 231 (2012), 1291-1307), that arose entirely by means of email correspondence, and to make accessible some excerpts from this correspondence in order to gain some insight into how the article evolved. This might be instructive in particular with regard to the students' own research ambitions.

Voraussetzungen / Besonderes	No prior knowledge of Coxeter exponents is required because some relevant stuff about Coxeter groups and root systems shall be explained in an early seminar talk.

401-3620-20L	Student Seminar in Statistics: Inference in Non-Classical Regression Models Maximale Teilnehmerzahl: 24 Hauptsächlich für Studierende der Bachelor- und Master-Studiengänge Mathematik, welche nach der einführenden Lerneinheit 401-2604-00L Wahrscheinlichkeit und Statistik (Probability and Statistics) mindestens ein Kernfach oder Wahlfach in Statistik besucht haben. Das Seminar wird auch für Studierende der Master-Studiengänge Statistik bzw. Data Science angeboten.	W	4 KP	2S	F. Balabdaoui
Kurzbeschreibung	Review of some non-standard regression models and the statistical properties of estimation methods in such models.
Lernziel	The main goal is the students get to discover some less known regression models which either generalize the well-known linear model (for example monotone regression) or violate some of the most fundamental assumptions (as in shuffled or unlinked regression models).
Inhalt	Linear regression is one of the most used models for prediction and hence one of the most understood in statistical literature. However, linearity might too simplistic to capture the actual relationship between some response and given covariates. Also, there are many real data problems where linearity is plausible but the actual pairing between the observed covariates and responses is completely lost or at partially. In this seminar, we review some of the non-classical regression models and the statistical properties of the estimation methods considered by well-known statisticians and machine learners. This will encompass: 1. Monotone regression 2. Single index model 3. Unlinked regression 4. Partially unlinked regression

401-3900-16L	Advanced Topics in Discrete Optimization Number of participants limited to 12.	W	4 KP	2S	C. Angelidakis, A. A. Kurpisz, R. Zenklusen
Kurzbeschreibung	In this seminar we will discuss selected topics in discrete optimization. The main focus is on mostly recent research papers in the field of Combinatorial Optimization.
Lernziel	The goal of the seminar is twofold. First, we aim at improving students' presentation and communication skills. In particular, students are to present a research paper to their peers and the instructors in a clear and understandable way. Second, students learn a selection of recent cutting-edge approaches in the field of Combinatorial Optimization by attending the other students' talks. A very active participation in the seminar helps students to build up the necessary skills for parsing and digesting advanced technical texts on a significantly higher complexity level than usual textbooks. A key goal is that students prepare their presentations in a concise and accessible way to make sure that other participants get a clear idea of the presented results and techniques. Students intending to do a project in optimization are strongly encouraged to participate.
Inhalt	The selected topics will cover various classical and modern results in Combinatorial Optimization. Contrary to prior years, a very significant component of the seminar will be interactive discussions where active participation of the students is required.
Literatur	The learning material will be in the form of scientific papers.
Voraussetzungen / Besonderes	Requirements: We expect students to have a thorough understanding of topics covered in the course "Mathematical Optimization".

401-3530-20L	Stokes Phenomenon and Isomonodromy Equations Findet dieses Semester nicht statt. Number of participants limited to 12. The seminar does not take place in the Spring Semester 2020.	W	4 KP	2S	G. Felder
Kurzbeschreibung	Ordinary differential equations with irregular singularities, Stokes phenomenon, isomonodromy deformations and appications.
Lernziel
Inhalt	This seminar is about the study of ordinary differential equations with poles and its application in mathematical physics. When a system of differential equations has an irregular singularity, such as a pole of order two or higher, a solution may fail to have a well-defined asymptotic expansion at the singular locus. Instead, there is a collection of angular sectors surrounding the singular locus, in each of which an asymptotic expansion is defined. The existence of such sectorial asymptotic expansions is what is called the “Stokes phenomenon”. The Stokes phenomenon has found remarkable applications in different areas of mathematics and physics, such as in cohomological field theory, the study of stability conditions, noncommutative Hodge theory, cluster algebras, quantum groups and so on. In particular, the Stokes phenomenon is the essential ingredient in an irregular version of the Riemann-Hilbert correspondence, where the moduli space of differential equations with irregular singularities is described in terms of its associated generalized monodromy data (Stokes matrices). Moreover, the crucial role of the Stokes phenomenon in the study of representation theory and integrable systems is only beginning to emerge. The first 9 talks will include a general introduction to Stokes phenomenon and isomonodromy deformation. The last 3 talks of the seminar will focus on its applications.
