Kavliprisene er et samarbeid mellom Det norske videnskaps-akademi, Kavli Foundation (USA) og Kunnskapsdepartementet. Dette er tredje året prisene deles ut, og utdelingen finner sted i Oslo den 4. september 2012. I tillegg til selve utdelingen er det flere Kavlipris-arrangementer den første uken i september.

Atsushi Takeuchi (Uni. Osaka City) holder et seminar med tittelen: Positivity of Densities for Stochastic Differential Equations Driven by Gamma Processes

Over the last decades important methodological advances have been made for designing and analysing nested case-control and case-cohort studies. While some of these methodologies need further developments before they can be widely used, others have matured to a level that makes them ready to use in epidemiological practice. The focus of the workshop is on the methodologies that are ready to use. The workshop is aimed at biostatisticians and epidemiologists who work with population registry data and large cohorts studies. It is assumed that the participants are familiar with cohort and classical case-control studies and the regression models used to analyse them (logistic regression and Cox regression).

Patrick J. Lynett is from the University of Southern California.

Dávid Kunszenti-Kovács, Tübingen University (Germany) will give a talk with title "The Jacobs-deLeeuw-Glicksberg decomposition and ergodic theorems".

Abstract: We present the classical decomposition theorem for contractions on Hilbert spaces due to Jacobs, deLeeuw and Glicksberg, and show how it can be used to prove ergodic theorems. We then prove a new version of this decomposition, adapted to the context of W*-algebras, with consequences for W*-dynamical systems. Finally we take a look at how the characterizations given in the original decomposition theorem can be further strengthened.  

John Quigg, University of Arizona (Tempe), USA, will give a talk with title "Exotic group C*-algebras"

Abstract: We study C*-algebras between C*(G) and C*_r(G), focusing on the aspects relevant to noncommutative crossed-product duality.  

I august 2012 er det femti år siden Norge ble en romnasjon. Inngangen i 1962 ble den første forskningsraketten, Ferdinand 1, som ble skutt opp fra Andøya Rakettskytefelt. Dette blir markert på Andøya den 16.-19. august med konferanser, seminar og et åpent program. Instituttene for geofag, teoretisk astrofysikk, og fysikk vil delta under markeringen under parolen UiO i rommet.

Portfolio optimization based on pair-copula constructions

Friday seminar by Jeffrey A. Hutchings

CEES Extra seminar by Anna Kuparinen

Jeg vil snakke om en flettet monoidal diagram kategori av B-rom, Quillen ekvivalent til simplisielle mengder, der kommutative monoider svarer til doble løkkerom i simplisielle mengder. For enhver liten flettet monoidal kategori har jeg konstruert en kommutativ B-roms monoide slik at homotopigrensen av den er svakt ekvivalent til nerven av den flettede monoidale kategorien.Dette gir en modell for alle doble løkkerom siden Fiedorowicz, Stelzer og Vogt viser at alle doble løkkerom er svakt ekvivalente til en nerven av en flettet monoidal kategori i en artikkel fra september 2011.
