Donaldson-Thomas theory is a well-celebrated modern tool for studying Calabi-Yau threefolds. In this theory, one studies weighted Euler characteristics of moduli spaces of sheaves on threefolds. Elliptic genus on the other hand is a refinement of Euler characteristic motivated by a hypothesis of Witten. In this talk I will discuss and present evidence of a surprising relationship between the two. That is, a relationship between the Elliptic genus of sheaves surfaces and the Donaldson-Thomas theory of elliptically fibred threefolds.

Department seminar. Dario Tortarolo is an Assistant Professor of Economics at the University of Nottingham and a Research Associate at the Institute for Fiscal Studies. He will present the paper: "Can VAT Cuts Dampen the Effects of Food Price Inflation?" (written with Youssef Benzarti and Santiago Garriga).

On Thursday the 11th of May at 13:30, we host a double AQUA/CEES seminar! Katerina Guschanski and David Richardson are visiting our department as opponents for the disputation of Oliver Kersten and they were happy to give a talk the day before.

Til minne om Norges fremste astrofysiker og grunnlegger av Institutt for teoretisk astrofysikk, professor Svein Rosseland (1894 ¨C 1985), arrangerer Institutt for teoretisk astrofysikk hvert ?r en Rosselandforelesning.

This talk will introduce a recent suite of research focussed on the statistical detection of anomalous structure in online data settings. The challenge of efficiently identifying anomalies in data sequences is an important statistical problem that now arises in many applications. Whilst there has been substantial work aimed at making statistical analyses robust to outliers, or point anomalies, there has been much less work on detecting anomalous segments, or collective anomalies, particularly in those settings where point anomalies might also occur. This is the challenge we seek to address, demonstrating theoretical results in both the offline and online settings as well as introducing some applied case studies.
