[:is]Málstofa í stærðfræði Fyrirlesari: Sylvain Arguillère, CNRS – Institut Camille Jordan – MMCS Titill: Shape analysis through flows of diffeomorphisms Staðsetning: VR-II, V-258Tími: fimmtudagur 13. júní kl. 11.00 Ágrip: The goal of shape analysis is to compare shapes in a way that takes into account their geometric properties. The end goal is to give an […]

We consider the edges to be oriented, and EX is equipped withan involution which inverts the

[:is]Málstofa í stærðfræði Fyrirlesari: Giulio Cerbai, University of Florence Titill: Sorting Permutations Using Pattern-Avoiding Stacks Staðsetning: Tg-227 Tími: Fimmtudagur 9. maí kl. 11.40 Ágrip: The problem of sorting a permutation using a stack was proposed by Knuth in the 1960s. As it is well known, sortable permutations can be characterized in terms of pattern avoidance

[:is]Málstofa í stærðfræði Titill: Families of peak functions and exposing maps in strictly pseudoconvex domains Fyrirlesari: Arkadiusz Lewandowski, Jagiellonian University Staðsetning: Tg-227 Tími: Fimmtudagur 2. maí kl. 11.40 Ágrip: It is known that given a smooth strictly pseudoconvex domain, all of its boundary points admit a peak function and an exposing map. We shall discuss

Next, we will review a recent joint work with Chinh H. Lu and Vincent Guedj on a

Staðsetning: VR-II 258Tími: Fimmtudagur 21. mars kl. 11.40 Ágrip: Hydrodynamics is one of the most successful theories in physics which describe dynamics across various length scales: from a few micrometers to the scale of galaxies.
