Alexander Müller-Hermes will give a talk with title: Capacities of quantum channels
We are delighted to finally again be able to invite you to the Klækken seminar, October 11 – October 12, 2022. Klækken seminar is open for young researchers in temporary positions within statistics/biostatistics/bioinformatics at OCBE (UiO and OUS), Institute of Mathematics (UiO), BiAs (NMBU) and RealTek (NMBU). It is meant as an arena to get to know each other across the institutes and to practice your presentations skills in front of a friendly and harmless audience.
In 80s Weibel observed that K-theory is homotopy invariant on Fp-schemes up to p-torsion. His main tool was the action of the ring Witt vectors on nil-K-groups: NKi(R) = Ker(Ki(R[t]) → Ki(R)). We will revisit the proof and check that the same result holds for all finitary localizing invariants.
Stephen Hladky presents work in collaboration with Margery A. Barrand (both Department of Pharmacology, University of Cambridge).
Abstract: Extravascular fluxes of marker substances and some wastes are sufficiently fast that there is almost certain to be a component of flow augmenting their diffusion in the parenchyma. There have been two major proposals for how this flow is produced and where it is important. The evidence for the classical and glymphatic hypotheses will be reviewed. Extravascular, and in particular perivascular, routes for fluid movement out of the parenchyma to lymphatics may be important in the development of hydrocephalus.
I will explain how motivic homotopy theory can be used to attack problems regarding finite projective modules over smooth affine k-algebras. I will recall in particular the foundational theorem of Morel and Asok-Hoyois-Wendt, and the construction of the Barge-Morel Euler class. Time permitting, I will explain recent progress on Murthy's splitting conjecture.

Financial risk arising from the increasing of life expectancy. This is all in a nutshell. To know more, come to the lecture: forecasting, modelling, quantification.
We combine a systematic approach for deriving general a posteriori
error estimates for convex minimization problems using convex duality relations with a recently derived generalized Marini formula. The resulting a posteriori error estimates are essentially constant-free and apply to a large class of variational problems including the p-Dirichlet problem, as well as degenerate minimization, obstacle and image de-noising problems.
For the p-Dirichlet problem, the a posteriori error bounds are equivalent to the classical residual type a posteriori error bounds and, hence, reliable and efficient.

A conference in honour of Nils Henrik Risebro on the occasion of his 60th birthday.
Doctoral candidate Dennis Schroers at the Department of Mathematics will be defending the thesis New Topics in Nonlinear Functional Data Analysis for the degree of Philosophiae Doctor.
José Carlos Nieto Borge is a marine physicist and associate professor at the Universidad de Alcalá de Henares, Spain.
A four-days workshop to appreciate and discuss advances in risk and stochastics with a close look into applications and numerical methods
We consider the linearized elasticity equations, discretized using multi-patch Isogeometric Analysis. To solve the resulting linear system, we choose the Dual-Primal Isogeometric Tearing and Interconnecting (IETI-DP) Method with a scaled Dirichlet preconditioner. We are interested in a convergence analysis. See more details below.
We will present the results of numerical experiments that demonstrate our theoretical findings.
Professor Elaine Cohen (University of Utah) is appointed honorary doctor at UiO. On this occation she will give a lecture: Mathematics and Geometric Modeling: Similar Ingredients, Distinct Goals
I will discuss the question in the title. This is joint work with Alex Degtyarev and Ilia Itenberg. This will be a talk involving very classical topics in algebraic geometry. I will try to make the talk accessible to students at master- and PhD level.
