-
(Research report / Forskningsrapport, 2001)We introduce and study several amenability properties for unitary corepresentations and *-representations of algebraic quantum groups, which may be used to characterize amenability or co-amenability of such groups. As a ...

On an adaptive version of the Metropolis-Hastings algorithm with independent proposal distribution (Research report / Forskningsrapport, 2000)
-
(Research report / Forskningsrapport, 2005)A well-studied one-dimensional model for the operation of clarifier-thickener units in engineering applications can be expressed as a conservation law with a flux that is discontinuous with respect to the spatial variable. ...
-
(Research report / Forskningsrapport, 2003)We derive arbitrage-free pricing dynamics for claims on temperature, where the temperature follows a fractional Ornstein-Uhlenbeck process. Using a fractional white noise calculus, we can express the dynamics as a special ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Artificial Intelligence (AI) has the potential to greatly improve the delivery of healthcare and other services that advance population health and wellbeing. However, the use of AI in healthcare also brings potential risks ...

(Research report / Forskningsrapport, 2001)We prove an existence and uniqueness result for a general class of backward stochastic partial differential equations. This is a type of equations which appear as adjoint equations in the maximum principle approach to ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)In this paper we provide explicit upper and lower bounds on certain L2n-widths, i.e., best constants in L2 approximation. We further describe a numerical method to compute these n-widths approximately and prove that this ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)We initiate the study of the internal structure of C*-algebras associated to a left cancellative semigroup in which any two principal right ideals are either disjoint or intersect in another principal right ideal; these ...
-
(Master thesis / Masteroppgave, 2011)Vi betrakter en gruppevirkning av G på en mengde X. Opgaven omhandler C*-algebraer relatert til den uniforme Roe-algebraen. Vi bruker konstruksjoner fra kryssprodukter av C*-algebraer til å konstruere en analog til den ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Previous-30 treatments of multivariate non-causal time series have assumed stationarity. In this article, we consider integrated processes in a non-causal setting. We generalize the Johansen–Granger representation for ...
-
(Research report / Forskningsrapport, 2012)In an L<sub>2</sub>-framework, we study various aspects of stochastic calculus with respect to the centered doubly stochastic Poisson process. We introduce an orthogonal basis via multilinear forms of the value of the ...
