Abstract: Let O be a compact reflection n-orbifold whose underlying space is homeomorphic to a truncation n-polytope, i.e. a polytope obtained from an n-simplex by successively truncating vertices. In this talk, I will give a complete description of the deformation space of convex real projective structures on the orbifold O of dimension at least 4. Joint work with Suhyoung Choi and Ludovic Marquis.

Im Rahmen des Mini-Workshops präsentieren die Teilnehmer*innen von das Seminar "Coding Challange" ihre Ergebnisse zu einer zuvor individuell bearbeiteten Problemstellung. Jede*r Teilnehmer*in hat sich eigenständig mit einer von mehreren vorgegebenen Aufgaben auseinandergesetzt. Ziel des Seminars war es, durch selbstständige Literaturrecherche sowie durch Anwendung im Studium erlernter analytischer und numerischer Methoden geeignete…

Let p be a prime and n a positive integer. On the one hand, one can consider representations on characteristic p vector spaces of the topological group GL_n(Q_p), where Q_p is the field of p-adic integers. On the other hand, one can consider representations on characteristic p vector spaces of dimension n of the absolute Galois group of Q_p. We will illustrate a conjectural duality between these two kinds of representations, in the…
The lecture will be held by Prof Ingrid Daubechies. Prof Daubechies is James B. Duke Professor at Duke University and was previously Professor and Director of the Department of Mathematics at Princeton University. Her fundamental contributions to the theory and application of wavelet methods are of fundamental importance in many fields from applied mathematics to concrete technical implementations. She has received numerous awards for her work,…
Abstract: In this talk we will discuss Coxeter groups and their "Vinberg representations". These are discrete and faithful representations that are of special geometric significance. As we will show, the Zariski-closure of such representations is very restricted. This allows us to construct new examples of Zariski-dense subgroups of SL(n,Z). In particular, we will prove that, for all n at least 3, SL(n,Z) contains a Zariski-dense subgroup…
Title: Quiver Grassmannians for the Bott-Samelson resolution of type A Schubert varieties
Abstract: Quiver Grassmannians are projective varieties parametrising subrepresentations of quiver representations. Their geometry is an interesting object of study, due to the fact that many geometric properties can be studied via the representation theory of quivers. In this talk, we construct a special…
Title: Linear Disjointness, Relativised Cyclotomic Polynomials and Inflated G-extensions for Number Fields
Abstract: There had been many attempts to generalize cyclotomic polynomials by many authors: combinatorialapproach using MOebius Inversion, Number-Theoretic approacj=h by focussing on unitary divisors etc. Our approach takes the factorization of X^n-1 as the model and defines cyclotomic…
Abstract:
Die gymnasiale Oberstufe hat in den letzten Jahrzehnten einen stetigen Zulauf erfahren, sodass die Abiturientenquote eines Altersjahrgangs heute bei etwa 40 Prozent liegt. Dadurch nimmt sie einen immer bedeutenderen Platz im institutionalisierten schulischen Bildungsangebot ein, weshalb eine (erneute) wissenschaftliche Auseinandersetzung mit den Bildungszielen und den Wirkungen des Unterrichts in der gymnasialen Oberstufe sinnvoll…
