I will discuss the “geometric method” for syzygies and discuss applications to the study of tautological bundles of linear spaces. From this, I will explain how to pass from realizable matroids to all matroids via initial degenerations. This is joint work in progress with Alex Fink and Chris Eur.

Doctoral candidate Rebecca Anne Robinson at the Institute of Theoretical Astrophysics, Faculty of Mathematics and Natural Sciences, is defending the thesis "Magnetic characteristics of quiet Sun nanoflares" for the degree of Philosophiae Doctor.

Title: The connection between the Atlantic Multidecadal Variability and Indian summer rainfall: a review

Speaker: Fei Fei Luo, Chengdu University

SPARK Norway Educational Forum are monthly open meetings organized by UiO:Life Science and SPARK Norway partners.

A finite graph determines a Kirchhoff polynomial, which is a squarefree, homogeneous polynomial in a set of variables indexed by the edges. The Kirchhoff polynomial appears in an integrand in the study of particle interactions in high-energy physics, and this provides some incentive to study the motives and periods arising from the projective hypersurface cut out by such a polynomial.

From the geometric perspective, work of Bloch, Esnault and Kreimer (2006) suggested that the most natural object of study is a polynomial determined by a linear matroid realization, for which the Kirchhoff polynomial is a special case.

I will describe some ongoing joint work with Delphine Pol, Mathias Schulze, and Uli Walther on the interplay between geometry and matroid combinatorics for this family of objects.

Doctoral candidate Manuel Carrer at the Department of Chemistry, Faculty of Mathematics and Natural Sciences, is defending the thesis "From All-Atom To Mesoscale: Bridging The Gap With Differentiable Molecular Dynamics" for the degree of Philosophiae Doctor.

Welcome to a two-day event in Oslo. The event will cover the broad topics of ageing and dementia, in particular Alzheimer’s and Parkinson’s diseases, at molecular, individual, and societal levels.

Eli Bæverfjord Rye will defend her thesis “Searching for chargino–neutralino pair production in √s = 13 TeV pp collisions with the ATLAS detector” for the degree of Philosophiae Doctor at the University of Oslo, Faculty of Mathematics and Natural Sciences.

Welcome to the GEOHYD Lunch Seminar Friday 15th of September @ 12:15 in Aud. 1, Geology building, or via video link using Zoom. The seminar is held by Olivier Gagliardini, Université Grenoble Alpes.

Innovations in fluid mechanics are leading to better food since ancient history, while creativity in cooking inspires applied and fundamental science. In this talk, I will discuss how recent advances in hydrodynamics are changing food science, and how the surprising phenomena that arise in the kitchen lead to discoveries and technologies across the disciplines, including rheology and soft matter. Central topics include cocktails and champagne (multiphase flows), whipped cream (complex fluids) and pancake making (viscous flows). For every topic, I will present the state-of-the-art knowledge, the open problems, and likely directions for future research.

Abstract: TBA

Ragnhild Aurvik, Ph.D student at Institute of Theoretical Astrophysics, University of Oslo.

In this talk, I explain how we explicitly construct a motivic analog of the fundamental group of the circle. We construct a group structure on the set of pointed naive homotopy classes of maps from the Jouanolou device to the projective line. The group operation is defined via matrix multiplication on generating sections of line bundles and only requires basic algebraic geometry. In particular, it is completely independent of the construction of the motivic homotopy category. Based on joint work with William Hornslien, Gereon Quick, and Glen Matthew Wilson.
