22. febrúar, kl. 11:40, í Oddi O-106. Fyrirlesari: Sigurður Freyr Hafstein, Háskóli Íslands Titill: Contraction Metrics and their numerical computation, Part 2 Ágrip:  Similar to Lyapunov functions, Contraction Metrics can be used to characterize the long term behavior of dynamical systems.  We will discuss what they are, their relation to Lyapunov functions, and how they

Málstofa: Einar Bjarki Gunnarsson

October 6, 11:40 Room N-130 Speaker: Ejnar Bjarki Gunnarsson (University of Iceland) Title: The site frequency spectrum of a neutrally evolving tumor Abstract: The site frequency spectrum (SFS) is a popular summary statistic of genomic data, recording the frequencies of mutations within a given population. While the SFS of a constant-sized population undergoing neutral mutations

Málstofa í stærðfræði Fyrirlesari: Brittany A. Erickson Titill: A Finite Difference Method for Plastic Response with an Application to the Earthquake Cycle Staðsetning: V-157, VR-II. Tími: Mánudagur 8. ágúst kl. 13:20. Ágrip: We are developing an efficient, computational framework for simulating multiple earthquake cycles with off-fault plastic response. Both rate-independent and viscoplasticity are considered, where

Málstofa í stærðfræði Fyrirlesari: Sylvain Arguillère Titill: Constrained Shape Analysis Through Flows of Diffeomorphisms Staðsetning: TG-227 (Tæknigarður, 2. hæð) Tími: Föstudagur 24. júní kl. 13:20. Ágrip: The general purpose of shape analysis is to compare different shapes in a way that takes into account their geometric properties, such as smoothness, number of self-intersection points, convexity…

Málstofa í stærðfræði Fyrirlesari: Luis L. Bonilla, Universidad Carlos III de Madrid Titill: Hybrid modeling of tumor induced angiogenesis Staðsetning: VR-II, 158. Tími: Fimmtudagur 9. júlí, klukkan 13:30-14:30. Ágrip: Angiogenesis is the formation of blood vessels induced by a deficit of oxygen in tissues. It is a basic process in wound repair, formation of vessel
