Málstofa í stærðfræði Speaker: Gestur Ólafsson, Louisiana State University Title: Discretization and atomic decomposition of Bergman spaces Staðsetning: Naustið, Endurmenntun (hér) Tími: Fimmtudagur 16. apríl, klukkan 15:00-16:00. Ágrip: We will discuss how representation theory can be used to construct invariant Banach spaces and functions. This theory goes back to the work of Feichtinger and Gröchenig
Málstofa í stærðfræði Fyrirlesari: David Lowe Titill: Cosmology from conformal field theory Staðsetning: VR-156 Tími: Þriðjudagur 31. febrúar, frá 15:00-16:00. Ágrip: Our universe appears to be entering a de Sitter phase, where expansion becomes dark energy dominated. In this limit, the isometries of the spacetime are the same as the conformal group. There exists an
