"Kompetenzorientierter Mathematikunterricht" - Was kann das bedeuten?
Tuesday, 14.1.14, 19:30-20:30, Hörsaal II, Albertstr. 23b
Aktuelle Lehr- und Bildungspläne in Mathematik orientieren sich an den Bildungsstandards und sind „kompetenzorientiert“, d.h. Schülerinnen und Schüler sollen anhand von zentralen mathematischen Inhalten gewisse mathematische Fähigkeiten wie Argumentieren, Problemlösen oder Modellieren erwerben. Das A und O hierfür ist ein guter Mathematikunterricht. Im Vortrag werden anhand zweier Unterrichtsstunden bzw. -einheiten aus Klasse 8 (Realschule) bzw. Klasse 10 (Gymnasium) einige wesentliche Elemente eines qualitätsvollen, „kompetenzorientierten“ Mathematikunterrichts herausgearbeitet und erläutert. Dazu gehören u.a. die geistige Aktivierung aller Schülerinnen und Schüler sowie die Vermittlung von Strategien. Zudem wird aufgezeigt, wie wichtig diagnostische Kompetenzen der Lehrerinnen und Lehrer sind. Abschließend werden einige naheliegende Folgerungen für die Lehrerbildung gezogen.

Classifying superconformal field theories via chiral rings
Monday, 20.1.14, 16:15-17:15, Raum 404, Eckerstr. 1
I will introduce some of the main mathematical ideas behind N=2 superconformal field theory, using the N=2 minimal models as a concrete example, and explore some of their connections to geometry. \n\nTo illustrate these ideas I will focus on the so-called "chiral rings", which arise from basic Lie algebra representation theory plus ideas from quantum field theory. I show how the chiral rings relate to Calabi-Yau geometry, then I'll describe how chiral rings appear in Cecotti and Vafa's famous ADE singularity classification of a special subclass of N=2 minimal models (those with "space-time supersymmetry"), and we'll briefly reacquaint ourselves with some other prominent appearances the ADE pattern in maths and physics.\n\nFinally I'll present the chiral rings of the entire class of N=2 minimal models (when the extra assumption of space-time supersymmetry is dropped) and report on ongoing work with K. Wendland concerning a geometric classification of these theories.\n
A Variant of the C0 Interior Penalty Method for the Biharmonic Equation
Tuesday, 21.1.14, 14:15-15:15, Raum 226, Hermann-Herder-Str. 10
We consider a symmetric interior penalty method for the Biharmonic Problem which weakly over-penalizes the jumps of the normal derivatives across element boundaries and which can handle meshes with hanging nodes. The notion of meshes generated by independent refinements will be introduced and a general analysis of piecewise H2-functions associated with those meshes will be presented. We derive a priori error estimates in the energy norm and the L2-norm for a class of meshes generated by independent refinements and demonstrate the performance by numerical results.

Using semigroups to study coupled cell networks
Thursday, 23.1.14, 17:00-18:00, Hörsaal II, Albertstr. 23b
Dynamical systems with a coupled cell network\nstructure arise in applications that range from statistical\nmechanics and electrical circuits to neural networks,\nsystems biology, power grids and the world wide web.\n A network structure can have a strong impact on the\nbehaviour of a dynamical system. For example, it has been\nobserved that networks can robustly exhibit (partial)\nsynchronisation, multiple eigenvalues and degenerate\nbifurcations. In this talk I will explain how semigroups\nand their representations can be used to understand and\npredict these phenomena. As an application of our theory, I\nwill discuss how a simple feed-forward motif can act as an\namplifier.\n This is joint work with Jan Sanders.

Methodos
Tuesday, 28.1.14, 19:30-20:30, Hörsaal II, Albertstr. 23b
Methodos ist eine Gruppe von Schülerinnen und Schülern, die sich selbstständig auf die externe Abiturprüfung in Baden-Württemberg vorbereiten. Sie übernehmen Planung und Organisation aller Aufgaben, die für diese Vorbereitung notwendig sind, weil sie ihr Lernen gestalten und für ihre Bildung selbstverantwortlich sein wollen. Dafür haben sie sich von der Regelschule abgemeldet. Sie mieten Unterrichtsräume und stellen Lehrer ein (und entlassen sie gegebenenfalls auch). Sie versuchen individuelles Lernen und Arbeiten in der Gruppe fruchtbar miteinander zu verbinden.\nSimon Valentin und Dieter Markert berichten aus Schüler- und Lehrerperspektive von ihren Erfahrungen bei Methodos.\n

Tilting and Parity
Friday, 31.1.14, 10:15-11:15, Raum 404, Eckerstr. 1
In the representation theory of reductive groups in positive\ncharacteristic, there is a very special class of objects called tilting\nmodules. Two important theorems state that the class of tilting modules\nis closed under tensor product and restriction to Levi subgroups.\n\nSimilarly, on (generalized) flag varieties, there is a special class of\ngeometric objects called parity sheaves. I will explain two newer\ntheorems that are analogues of the tensor product and restriction\ntheorems mentioned above.\n\nThe main goal of the talk will be to explain how these two pictures fit\ntogether.\n\nThis is based on joint work with Daniel Juteau and Geordie Williamson.
