Wir wollen wir uns mit den Grundlagen der Mathematik
beschäftigen, die in den grundlegenden Veranstaltungen angesprochen wurden,
für deren umfassende Behandlung aber keine Zeit blieb. Wir werden dafür
wichtige Konzepte und bedeutende Sätze in den drei Bereichen Mengenlehre,
Logik und Kategorientheorie studieren. Wir werden uns mit den Axiomen der
modernen Mengenlehre beschäftigen, die Bedeutung (und die Mängel) von
Cantors Definition einer Menge untersuchen und das berühmte Auswahlaxiom
studieren. Wir werden verschiedene Zahlenräume konstruieren und Ordinal-
und Kardinalzahlen kennenlernen sowie verschiedene Stufen der Unendlichkeit
betrachten. Wir werden formale Sprachen untersuchen und uns mit der Logik
von mathematischen Beweisen beschäftigen und lernen, wie man diese formal
rechtfertigen kann.
Letztlich beschäftigen wir uns mit Kategorien. Viele Konzepte der Mathema-
tik trifft man in ähnlicher Form in verschiedenen Bereichen der Mathematik
wieder, denken Sie etwa an lineare Abbildungen, Gruppenhomomorphismen
oder stetige Abbildungen. Allen drei ist gemein, dass es sich um strukturer-
haltende Abbildungen handelt, obwohl die jeweiligen Strukturen kaum etwas
miteinander zu tun haben. Wir werden lernen, wie man solche Konzepte
unter einem Begriff subsumieren kann. Außerdem werden wir uns universelle
Konstruktionen anschauen und untersuchen, wie man Begriffe, die wir von
Mengen her kennen, in andere Gebiete der Mathematik sinnvoll übertragen
kann.

Voraussetzungen:
Keine Vorkenntnisse erforderlich, nur ein Interesse an logischen und formellen
Konzepten.
Die Vorlesung richtet sich an alle Studierenden, die ihr Verständnis der
Mathematik vertiefen und ein tieferes Verständnis der Grundlagen erlangen
möchten.

Are you fascinated by geometric shapes and their properties?
Are you an Bachelor's or Masters's student in mathematics looking to deepen your understanding of polytopes?
Then this seminar is for you!

In this seminar, we will delve into the fascinating world of polytopes, which are geometric objects that generalize the idea of a convex polygon or a convex polyhedron.
Polytopes have a wide range of applications in various fields, such as computer graphics, physics, and optimization.

We will cover a variety of topics related to polytopes, including:

• Basics of polytopes: We will begin by discussing the basic properties of polytopes. We will also explore the different types of polytopes, including simplices, cubes, and cross-polytopes.
• Combinatorial properties: We will delve into the combinatorial properties of polytopes, including the Euler characteristic, face numbers, and the Dehn-Sommerville equations.
• Algebraic properties: We will examine the algebraic properties of polytopes, including their symmetry groups and the representation of polytopes by linear inequalities.

- Applications: We will explore the different applications of polytopes in other areas of mathematics and science, such as linear programming, coding theory, and computer graphics.

• Computational methods: We will learn about computational methods for dealing with polytopes, including convex hull algorithms, triangulation algorithms and algorithms for counting the number of faces of a polytope.

Throughout the seminar, we will use examples and case studies to illustrate the concepts and theories discussed.
The seminar will also touch on the recent developments in the study of polytopes, including new results and open problems.

But this seminar is not just about listening and taking notes, we want you to actively participate in the class.
Each student is expected to give a talk on a specific topic related to polytopes, allowing you to not only deepen your own understanding but also share your knowledge with your peers.
This seminar is also a great opportunity for students to connect with other students with similar interests and to learn from each other.

Join us on a journey of discovery and exploration as we uncover the hidden beauty and complexity of polytopes.

In real data analysis, researchers are often interested in using the same data set to make inference on multiple hypotheses. For instance, they may want to identify brain regions that are activated by a stimulus in brain imaging data, or biological pathways that are differentially expressed in genomics data. However, testing multiple hypotheses simultaneously is a non-trivial extension of the individual case.

Indeed, any hypothesis test carries the risk of making a type I error, i.e., falsely rejecting a true hypothesis; this leads to a ‘false discovery’ and so a potentially misleading scientific result. Standard methods for testing an individual hypothesis allow to bound the probability of making such an error by an ‘acceptable’ risk, usually set at 0.05. When performing multiple tests, however, each one has a probability of producing a type I error. As a result, the risk of having at least one error among the findings may become unmanageable.

In this seminar we will introduce the problem of multiple testing and explore different techniques that have been proposed to control the flood of type I errors that arise in this context. We will see that different procedures aim at controlling different generalizations of the type I error. First, we will focus on procedures that control either the familywise error rate (FWER) or the false discovery rate (FDR), a class that includes many of the most popular multiple testing methods. Subsequently, we will introduce recent proposals that estimate the false discovery proportion (FDP) or provide confidence intervals for it.

The seminar is held in English.
