This week we have the pleasure of having Anne Marthine Rustad and Signe Riemer-Sørensen from SINTEF and the Mathematics and Cybernetics department.

SINTEF is a very important employer in our field of study and we look forward to hear about exciting research and job possibilities. Earlier this semester we forwarded several summer job options from SINTEF. 

Mathijs Janssen (University of Oslo): Electrolyte relaxation near electrified surfaces—from flat plates to nanoporous supercapacitors

Doctoral candidate Xiaojie Zhu at the Department of informatics, Faculty of Mathematics and Natural Sciences, is defending the thesis Privacy-preserving computation over outsourced dataset for the degree of Philosophiae Doctor.

In a famous paper, Geir Ellingsrud and Stein Arild Strømme use the Atiyah-Bott localization theorem in equivariant cohomology to compute the number of complex twisted cubics on a complete intersection. Motivated by results from A1-homotopy theory there is a new way of doing such enumerative counts which works over an arbitrary base field, not only the complex numbers. Recently, Marc Levine proved a version of Atiyah-Bott localization for this new way of counting.

In the talk I will recall the classical Atiyah-Bott localization theorem and explain how one can use it in enumerative geometry. Furthermore, I will explain how this new way of counting works and present some results about twisted cubics on complete intersections counted this way. This is based on joint work with Marc Levine.

Go on exchange to the world's northernmost campus, 78 ° north! As a science student at UiO, you can take courses at the University Center on Svalbard (UNIS) as part of your degree.

Philip Sørli Niane is master of Science student in CS:physics, 2nd year. Pizza thereafter and plenty of time for discussions. This is also a topic of interest for potential master of science thesis projects.

Statistics courses typically come in two different flavors:

1) A first type of course seeks deep understanding based on mathematical reasoning and proofs.

2) A second type of course focuses on practical applications, primarily based on fixed recipes without delving into underlying details.

3) I will here propose a third way, which seeks understanding of fundamental concepts, but through programming and simulation instead of mathematical proofs. This third way is thus geared towards students that have a stronger background in programming than mathematics, and that seek to understand the fundamentals as a basis for developing statistical analyses and data science methodology. This third way would also exploit its basis in programming to promote self-driven exploration, drawing inspiration from how computing has been integrated into science education through the long-running CSE initiative. I will provide examples ranging from how to explore the central limit theorem to performing Bayesian marginalization.

This research seminar presents the new EU-funded project JCOP (Joint Cybersecurity Operations Project) where IFI is a partner.

"Effect of Catchment Characteristics on Biodegradability of Dissolved Natural Organic Matter"

In the natural sciences we apply the scientific method in order to uncover the basic rules and principles that govern nature: we make observations, formulate hypotheses, test these hypotheses with experiments and develop theories. Rinse and repeat. But what if you are unable to conduct experiments? Or if the underlying rules suddenly change? These are the difficulties an economists are faced with. In my talk I hope to shed some light on general economic thought and how one goes about modelling “the economic machine” that emerges through human interaction. If the time allow, I will also provide an example of economic cost/benefit analysis done by Menon Economics for the Norwegian Coastal Administration.

Pizza after the seminar.

For the second talk, I will talk about how to relate relative Gromov--Witten invariants with relative periods via relative mirror symmetry and, given a degeneration, how relative periods and (absolute) periods are related on the mirror side.

Ph.d.-kandidat Henrik Eklund ved Institutt for teoretisk astrofysikk, Det matematisk-naturvitenskapelige fakultet, vil forsvare avhandlingen “Investigating dynamic small-scale events in the Sun with the Atacama Large Millimeter/sub-millimeter Array” for graden Philosophiae Doctor.

"Investigation of CYP activity in liver organoids by establishing a liquid chromatography-mass spectrometry method for measuring drug metabolism"

Magnus Fagernes Ivarsen will defend his thesis Plasma Irregularity Dissipation in the F-Region Ionosphere. Making Sense of the Decay and Subsequent Lifetimes of Turbulent Plasma Structures in the Ionosphere for the degree of Philosophiae Doctor.

The Hylleraas spring meeting is due to the Corona moved to September 20 - 22 at Hamn in Senja.

Industrial research and development are to a great extent the art of extending existing tools and methods with new techniques and data with the objective to optimise and improve operations. Expert Analytics is a Oslo based consultancy working in the fields of data and computational sciences, and in this presentation we will briefly tell you who we are and walk you through a few examples of what we have done for some of our clients. We will also present an internal product development project, where we make sense out of sensors, and where we're planning to open for summer internships next year for help with data exploration.

Doctoral candidate Christian Pedersen at the Department of Mathematics, Faculty of Mathematics and Natural Sciences, is  defending the thesis Elastohydrodynamic and capillary thin film flows at small scales for the degree of Philosophiae Doctor.
