Sylvia Frühwirth-Schnatter is a distinguished Austrian statistician and professor of applied statistics and econometrics at the Vienna University of Economics and Business. Renowned for her research in Bayesian analysis, she served as President of the International Society for Bayesian Analysis.

Professor Frühwirth-Schnatter has an impressive academic background, including a doctorate in engineering mathematics from TU Wien and previous positions at Johannes Kepler University Linz. Since 2011, she has been a full professor at the Vienna University of Economics and Business. She is also a Full Member of the Austrian Academy of Sciences.

Her research focuses on Bayesian econometrics, including Markov chain Monte Carlo methods and finite mixture models. She has received numerous accolades, including the WU Best Paper Award and the DeGroot Prize for her work on Markov switching models.

This workshop is part of QOMBINE, a cross-disciplinary project between mathematics, chemistry, and physics focusing on the mathematics for quantum computation. In this spirit, we want to bring together researchers with different backgrounds including quantum error correction, the quantification of decoherence, quantum Shannon theory and operator algebras. We hope that this will allow for discussions across disciplines leading to interesting new perspectives and collaborations on these topics.

In this talk I will cover the recent advances in the theory of power law distributions, in particular the role of Markov modulation and random stopping emphasized by Beare and Toda (2022), which builds on Nakagawa (2007)’s Tauberian theorem. Applications include the emergence of Zipf’s law in Japanese cities and the spread of COVID-19. I will also present open mathematical problems.

Donaldson-Thomas invariants "virtually" count curves in a given threefold. They factor into two parts: a part which only counts curves, and a degree 0 part, which counts 0-dimensional subschemes. The degree 0 part can be fully computed with a closed formula by relating them to combinatorial counting of plane partitions, which are certain configurations of boxes in 3D space. DT theory comes in various refinements. Nekrasov's formula refines the relation to counts of plane partitions to equivariant K-theoretic DT theory and gives a closed formula for refined degree 0 DT invariants.
 
Degree 0 DT invariants of orbifolds are related to counts of colored plane partitions, where the boxes are colored in a way determined by the orbifold structure. This allows the computation of closed formulas for some orbifolds. We refine these closed formulas to equivariant K-theoretic DT theory by modifying the techniques used in Okounkov's proof of Nekrasov's formula to work for orbifolds. We will explain these techniques in the case of schemes and describe some of the modifications to make them work for orbifolds.

Climate and weather can affect disease prevalence in different ways. For instance, humidity and temperature affect the life cycles of mosquitos which can greatly influence the prevalence of vector-borne diseases like malaria and dengue. Modelling this relationship is very important, both in the short term for outbreak preparedness, and in the long term, for health systems to adapt to the changing climate. However, this modelling is difficult because of low amounts of quality health data, complexities in spatial-temporal modelling, and the many different domains (vector biology, climate, epidemiology).
In this talk I will present our work on building a framework both for developing modularized and adaptable climate-health models, and for rigorously evaluating the utility of these models.
