Nordfjordeid Summer School 2026
The purpose of this workshop is to highlight applications of projective group representation theory and methods from operator algebras in quantum error correction.
Join us for the official launch of QSTAR, a new centre for quantum computing and applications hosted by SINTEF with UiO, NTNU, OsloMet, Simula, University of Copenhagen and RISE as research partners.
QOMBINE workshop on Quantum Information and Operator Systems
This was an internal workshop for the section of Statistics and Data Science at the department where we both discussed new/hot topics within statistics and discussed what we wanted with our section.
Organizers: Camilla Lingjærde, Yael Friedman, Johan de Aguas, Leiv Rønneberg, Clara Bertinelli Salucci
Professor Bernt Øksendal is a globally celebrated mathematician and pioneer in stochastic analysis and financial mathematics. His groundbreaking contributions, particularly in stochastic differential equations and their applications, have profoundly influenced research and education. His seminal textbook on stochastic differential equations remains a foundational resource for mathematicians worldwide.
Nordfjordeid Summer School 2025
Positive geometry is a recent branch of mathematical physics which present exciting connections with real, complex and tropical algebraic geometry.
In this talk, we introduce the topic by developing the positive geometry of del Pezzo surfaces and their moduli spaces.
We will analyze their connected components, likelihood equations and scattering amplitudes.
The talk is based on joint work with Early, Geiger, Sturmfels and Yun.
Abstract: I will introduce a certain configuration space associated with a graph, and compute its cohomology ring. It turns out to be related to internal zonotopal algebras, which were introduced in the context of approximation theory and show up in many different contexts.
This is joint work with Colin Crowley, Galen Dorpalen-Barry, and Andre Henriques.
Positroids are a class of matroids that were introduced by Postnikov in 2006 that index a certain stratification of the totally non-negative Grassmannian. These matroids are famously in bijection with a “zoo” of combinatorial objects including Grassmann necklaces and plabic graphs. We introduce a new family of positroids called rook matroids that arise from restricted rook placements on a skew shaped board and discuss it in terms of this zoo. We highlight the transversal structure of rook matroids and the slightly mysterious relationship they share with lattice path matroids. This is joint work with Per Alexandersson and ongoing work with Irem Portakal and Akiyoshi Tsuchiya.
Workshop at University of Oslo
Det tredje nasjonale matematikermøtet avholdes i Oslo i september 2024.
SCV conference 2024, remembering Nils Øvrelid
Welcome to the third Norwegian meeting on PDEs!
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.
The 5th Scandinavian Gathering Around Remarkable Discrete Mathematics
The AtLAST conference will be held in-person in Mainz, Germany, from 21 to 24 May 2024.
The purpose of this workshop is to bring together communities in dynamical systems, harmonic analysis and operator algebras whose research relates to point sets in Euclidean space and general locally compact groups.
Join us for the first NoRMAS meeting aimed at fostering collaboration and advancing research in the field of astronomy at long wavelengths, i.e infrared, (sub)millimeter and radio.
University of Oslo and University of Gothenburg invite to an informal workshop within machine learning with a focus on statistical aspects related to Machine Learning.
Phase tropical surfaces can appear as a limit of a 1-parameter family of smooth complex algebraic surfaces. A phase tropical surface admits a stratified fibration over a smooth tropical surface. We study the real structures compatible with this fibration and give a description in terms of tropical cohomology. As an application, we deduce combinatorial criteria for the type of a real structure of a phase tropical surface.
