For students at Exemplary studies

Valentino Picotti defends his PhD thesis: Language Support for Microservices Development.Professor Jacopo Mauro will act as chairman at the defence.

Speaker: Guillaume Laplante-Anfossi (University of Southern Denmark) Abstract:Given a curved A-infinity algebra and a bounding cochain (a.k.a Maurer—Cartan element), one can twist the former by the latter to get a new A-infinity algebra where the curvature is zero. This uncurving procedure plays a central rôle in Floer theory, where Fukaya categories are naturally curved objects. The goal of this talk will be to give a universal characterization of the procedure, using the theory of operads: we will show that the operad cMC, whose algebras are curved A-infinity algebras endowed with a Maurer—Cartan element, together with its natural morphism to the A-infinity operad, is terminal in a certain comma category. This category does not contain the Maurer—Cartan equation, thus the theorem provides a way to « rediscover » it as the answer to a universal (algebraic) problem. This is joint work with Adrian Petr and Vivek Shende.

Speaker: Christoph Nega (Technical University of Munich)Abstract: In my talk, I will discuss Feynman Integrals which are the cornerstone for precision computations in perturbative physics ranging from quantum field theory to classical general relativity. The two main examples will be self-energies in quantum electrodynamics and the scattering of black holes in a perturbative treatment of general relativity. I will introduce the relevant concepts in the context of Feynman Integrals, as integration by parts relations, master integrals, canonical integrals, iterated integrals and others. Moreover, I will show that Feynman Integrals are related to period integrals on geometries, particularly on Calabi-Yau varieties. This knowledge can be used to compute them. At the end, I will discuss methods to numerically evaluate the Feynman Integrals appearing in my examples.

The digital revolution has transformed the way we create, preserve, and access information, reshaping the role of archives in society.This talk explores the potential future of archives in the digital age, using one of the oldest philosophical archives and research institutes for philosophy in Germany – the Husserl Archives Cologne – as an example. Drawing on insights from phenomenology and digital humanities, it examines how digitalization challenges traditional notions of permanence, authenticity, and ownership. How do virtual repositories affect the human experience of accessibility and historical continuity? What implications does this have for cultural memory? About Thiemo BreyerThiemo Breyer is Professor of Phenomenology and Anthropology at the University of Cologne, where he also serves as Director of the Husserl Archives. He holds a PhD in Philosophy from the University of Freiburg and an M.Phil. in Social Anthropology from the University of Cambridge. He was visiting professor in Kyoto, Mainz, Milano, and Montreal, and research fellow at Harvard University. His research interests within the broader field of consciousness studies include affectivity, attention, embodiment, empathy, and memory. Venue: DIAS Auditorium Address: Fioniavej 34, 5230 OdenseOpen for all

Why is there a sudden and sharp drop in births occurring in so many countries in the 2010-20 decade?

Speaker: Michael Borinsky The Institute for Theoretical Studies (ETH-ITS), Zürich Abstract:I will present new results on the asymptotic growth rate of the Euler characteristic of Kontsevich's commutative graph complex. These results imply the same asymptotic growth rate for the top-weight Euler characteristic of M_g, the moduli space of curves, due to a recent work by Chan, Galatius and Payne. Further, they establish the existence of large amounts of unexplained cohomology in this graph complex. I will explain the role of this graph complex from the perspective of M_g's cohomology.
