Speaker: Guillaume Laplante-Anfossi (University of Southern Denmark)Abstract:The goal of this talk is to describe a strategy to compute algorithmically unstable homotopy groups of spheres modulo a prime number, using the theory of A-infinity algebras. This approach, which is based on Brown's theory of twisting cochains and its generalisation to A-infinity algebras by Kadeishvili, was proposed by Alain Prouté in 1986. One central ingredient that was missing at the time is a formula for the tensor product of A-infinity algebras and A-infinity morphisms, which are now available and were studied recently in combinatorics. In fact, these techniques can be used more generally to compute the homology of fibered spaces, and could potentially be used to develop a theory of Sullivan minimal models in characteristic p.

Speaker: Albert H. WernerUniversity of CopenhagenAbstract:Our ability to benchmark, verify, and control quantum devices ultimately rests on how well we understand their underlying dynamics. These dynamics are shaped not only by ideal Hamiltonian evolution, but also by time dependent effects and noise that arise in realistic settings. This talk will survey ideas for extracting meaningful dynamical descriptions of many qubit systems using simple, local measurements. Emphasis will be placed on how fundamental notions of locality limit the spread of information and make large scale quantum dynamics accessible through local data. The goal is to outline a set of ideas and methods that contribute to ongoing efforts to understand and characterize the dynamics of complex quantum devices.Location: D-IAS Aud.

This lecture will provide some historical perspective on the rise of protectionism in today’s world, drawing on evidence from the mercantilist period of the early modern period, as well as the 19th and 20th centuries.

Speaker: Ingo Runkel (​University of Hamburg)Abstract:TBA

Vækst og dens utilfredshedKapitalismens historie er uløseligt forbundet med vækstens historie. Vækst bliver ofte fremhævet som kapitalismens største bedrift, men den har også skabt bekymring. Malthus advarede om befolkningstryk, Jevons om udtømning af kul, mens Boserup foreslog, at knaphed kunne fremme innovation. Disse debatter minder os om, at vækst altid har været omstridt. I modsætning hertil tager meget af den moderne økonomi vækst for givet og fokuserer i stedet på at forfine metoder og estimere årsagssammenhænge. Dette seminar bringer vækst tilbage i centrum for debatten og spørger, hvordan historiske refleksioner over velstand og begrænsninger kan hjælpe os med at tænke over kapitalismens fremtid i en tid med klimakrise og ulighed.Der vil være korte oplæg fra et panel af eksperter med forskellige perspektiver:[list][*]Professor Carl-Johan Dalgaard, Københavns Universitet, https://dors.dk/raad-vismaend/formandskabet/carl-johan-dalgaard[*]Professor Eoin McLaughlin, Heriot-Watt University, https://www.eoinmclaughlin.ie/[*]Professor Wim Naudé, RWTH Aachen University,  https://www.wimnaude.com/[*]Professor Niklas Olsen, Københavns Universitet, https://researchprofiles.ku.dk/da/persons/niklas-olsen[/list]Efter oplæggene følger en paneldebat, modereret af Professor Søren Askegaard, DIAS, SDU.Bemærk: arrangementet foregår på engelsk

Speaker: Langwen Hui (University of Illinois)Abstract:TBA

In contemporary healthcare, everybody seems to want more data, on more people, and use them for ever more purposes. There are many good reasons for such ambitions, and yet it is becoming obvious that the current data intensification generates not just stories of benefit and success, but also complaints about misunderstandings, meaningless work, and unintended consequences. In his book, Data Paradoxes (MIT Pres, 2023), Klaus Hoeyer outlines and describes why we tell such different – almost opposing stories about data, and why very different stories might all be partly true. How can we use such insights productively – not least in an age where also cross-border data integration is high on the political agenda?Klaus Hoeyer is professor of Medical Science and Technology Studies at the Centre for Medical STS, University of Copenhagen. His research focuses on the links between policy, practice and experience in medical research and clinical practice. In recent years, he has focused mainly on the increased emphasis on collection, storage, use, reuse of health data, and how these data practices change the health services. This research is primarily financed by the European Research Council.

Speaker: Boris Kjær (​University of Copenhagen)Abstract:TBA

Over the past two decades, we have witnessed an explosion in the number of academic journals and publishers across most (if not all) research fields. This proliferation has placed significant strain on academics’ time (e.g., reviewing demands) and on university library budgets, and has raised pressing questions about both the quality and quantity of research outputs. Drawing on his personal experience as a former Editor-in-Chief of an Elsevier journal, as well as insights from a recent PNAS article on journal reform (https://doi.org/10.1073/pnas.2401231121), DIAS Chair Nikos Ntoumanis will open the session with reflections on why the current publication model is no longer fit for purpose and what reforms may be needed (or have recently been introduced). Following this short presentation, a panel discussion with DIAS colleagues Sergey I. Bozhevolnyi, Anthony Fernandez, Mette Præst Knudsen, and Lars Boje Mortensen, all of whom have editorial experience, will further explore the challenges and opportunities facing academic publishing today. We also look forward to hearing the audience’s views and experiences with current or alternative publication models.

Matthew Collins (biochemistry) and Lars Boje Mortensen (literary history) will speak about CODICUM, an ERC Synergy project which spans the humanities and the sciences. Their talk will cover books and book production before the advent of paper and print (before c. 1400 / 1450).You will be able to see (and perhaps touch) a real medieval parchment book and several fragments of such books (courtesy of the SDU library)!Lars will introduce pre-modern books and their significance for intellectual and literary history – particularly within the Nordic context of CODICUM. Next, Matthew will demonstrate some of the startling research possibilities that thousand year old animal skins offer through DNA analysis and protein profiles, and the new facility at SDU. Together, these approaches will unravel new patterns of book history, intellectual networks and surprising insights and applications of “biocodicology”.
