MATH+ Vortragsreihe: Dr. Nora Molkenthin

Dr. Nora Molkenthin, Max-Planck-Institut für Dynamik und Selbstorganisation, Göttingen Collective formation processes of dynamic networks Abstract : In systems with many units, the structure of their interaction often has significant impact on the behaviour of the system as a whole. Complex networks provide a unique tool for describing and investigating such systems, especially in the absence of symmetry. However, many of the available methods are more focused on specific static networks, while for many of the most interesting systems the interaction structure itself is subject to dynamical changes. In my work I have found many examples where the study of the dynamics giving rise to the interaction structures gave deep and novel insights into systems. In this talk I will focus on two examples from social networks and on-demand ride-sharing. The wide range of examples where this approach has been successful, leads to the question how these individual examples could be reflected in a wider theory for studying dynamical structure formation.

MATH+ Vortragsreihe: Dr. Nicolas Behr

Dr. Nicolas Behr, IRIF, Université Paris Diderot, France Rewriting theory for the social and life sciences Abstract : Somewhat surprisingly, despite the widespread use of models based upon transformations of graph-like objects in the applied sciences (chemical reaction systems, network models, random graph ensembles, tissue models, agent-based models, ...), the underlying theory and mathematics of so-called rewriting over adhesive categories appears to be relatively little known. In this talk, I will give a concise introduction to modern rewriting theory, and I will present two novel mathematical extensions of this framework: so-called rule algebras and tracelets for rewriting theories. Rule algebras permit to formulate a universal framework of continuous-time Markov chains arising from random transformation systems of graph-like structures, yielding a new tool-set for analyzing these systems, including in particular so-called combinatorial conversion (which permits to derive ODEs for the evolution of the statistical moments of pattern-counting observables). Tracelets on the other hand provide a mathematical formalism to extract high-level causal information from specifications of rewriting systems in terms of transformation rules and their base rates, sometimes referred to as "synthesis of explanations" (as opposed to the more standard approach of extracting statistical information from simulations). Originally developed as a precise mathematical implementation of the notion of pathways in biochemical reaction systems, this methodology aims to find high-level causal structures in sequences of rule compositions that permit to understand the dynamical behaviors of the typically highly complex random transformation system at hand. I will illustrate these novel concepts with application examples (such as a voter model of opinion formation) and provide some perspectives for high-performance software implementations of both the rule algebra and tracelet methodologies.

MATH+ Vortragsreihe: Dr. Sarah Wolf

Dr. Sarah Wolf, Global Climate Forum (GCF) Mathematik für Nachhaltigkeit - Entscheidungsunterstützung mit Hilfe agenten-basierter Modellierung Zusammenfassung: In meiner Forschung geht es um die Frage, wie Green Growth und eine nachhaltige Entwicklung erreicht werden können - ein Beispiel ist die derzeit viel diskutierte "Verkehrswende". Ökonomische Modelle, die in der Politikberatung vielfach eingesetzt werden, können oft per Konstruktion keinen Übergang aus einer gegebenen Ausgangslage hin zu einer strukturell veränderten Situation darstellen. Eine Alternative bieten agenten-basierte Modelle (ABM), die ein komplexes sozio-ökologisches Systems auf der Mikro-Ebene darstellen. Das Verhalten des Gesamtsystems betrachtet man dann mit Hilfe von Simulationen. Empirisch fundierte, hochaufgelöste ABM, die sich dazu eignen, mögliche Wege zu einer Verkehrswende (o.ä.) mit Stakeholdern zu diskutieren, bringen mehrere Herausforderungen mit sich: Die effiziente Parallelisierung solcher Simulationen ist weitgehend unerforscht, da die Interaktionsstrukturen der Agenten soziale Netzwerke mit geographischen Bedingungen mischen und daher von den (z.B. regelmäßigen Gitter-)Strukturen vieler HPC-Anwendungen abweichen. Die Analyse der Dynamik dieser Systeme wird dadurch erschwert, dass die Freiheit in der Wahl der Annahmen bei Definition und Implementierung eines Modells sehr groß ist. Mich interessieren grundlegende Modellstrukturen und Konzepte, mit denen man diese Herausforderungen angehen kann. Solche Modelle auf Basis von mathematischen Grundstrukturen sowohl einfacher implementieren als auch besser und schneller analysieren zu können, wäre nämlich hilfreich für eine wissenschaftliche Unterstützung von EntscheidungsträgerInnen. Diese können in "Decision Theatre"-Diskussionen mit dem Modell experimentieren und Folgen von verschiedenen Entscheidungen sofort eruieren. Umgekehrt können sie die weitere Modellentwicklung durch ihre Expertise aus der Praxis unterstützen.

Dr. Nataša Conrad, Zuse Institute Berlin Dynamische Systeme und Datenwissenschaften in den Sozial- und Geisteswissenschaften Abstract: In this talk, I will present my main research results on the topic of modeling, simulation and analysis of complex social systems. In particular, I will focus on the study of processes of change on/of these systems and approaches I have developed for their studying. I will demonstrate the applicability of these methods on real-world examples from humanities and social sciences.

Oliver Labs: Cubic Surface Models and their Historical and Mathematical Background

In the 19 th century, cubic surfaces - defined by an implicit equation of degree three in three variables - were among the first interesting examples in the development of modern algebraic geometry. A well-known result by Arthur Cayley and George Salmon is that any smooth cubic contains exactly 27 straight lines. Other prominent facts are the classification of all cubic surfaces w.r.t. their singularities by Ludwig Schläfli, and Alfred Clebsch's birational map between the plane and such surfaces where six points play an essential role. The talk will present both the historical and the mathematical background of classical hand-crafted and also recent 3d-printed cubic surface models. Some of their fascinating features such as the movement of the straight lines as the surfaces vary may very well be visualized using interactive software. In 2011 and 2014, the speaker created two versions of a complete series of more than 45 types of 3d-printed cubic surface models. Copies of these are now part of several university collections such as those at Lisbon, Strasbourg, Dresden, and Mainz, as well as at the IHP at Paris. He will bring some examples of these sculptures with him in order to illustrate facts which may better be appreciated when seeing and touching a real object.

The square peg problem is at least 106 years old and still unsolved in full generality. It asks whether any simple closed curve in the plane inscribes a square. By “inscribes a square” we mean that the curve contains the four vertices of a square. The square itself may intersect both the bounded and unbounded components. Substantial progress on the problem has been made using methods from equivariant topology: Piecewise linear, analytic, convex, and locally monotone curves are all known to inscribe squares. We present a recent positive result by T. Tao that takes an entirely different, “analytical” approach involving areas defined by line integrals and Stokes’ theorem.
