(Research report / Forskningsrapport, 2005)We derive error estimates for approximate (viscosity) solutions of Bellman equations associated to controlled jump-diffusion processes, which are fully nonlinear integro-partial differential equations. Two main results are ...
-
(Research report / Forskningsrapport, 2006)We derive error estimates for certain approximate solutions of Bellman equations associated to a class of controlled jump-diffusion (Lévy) processes. These Bellman equations are fully nonlinear degenerate integro-PDEs ...
-
(Research report / Forskningsrapport, 2007)We derive error estimates for finite difference-quadrature schemes approximating viscosity solutions of nonlinear degenerate parabolic integro-PDEs with variable diffusion coefficients. The relevant equations can be viewed ...
-
(Master thesis / Masteroppgave, 2013)In this master’s thesis we define a pricing model for futures contracts by using Lévy processes in an infinite dimensional Hilbert space H. The elements in H are assumed to be absolutely continuous functions on the positive ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Background Astrocyte endfoot processes are believed to cover all micro-vessels in the brain cortex and may play a significant role in fluid and substance transport into and out of the brain parenchyma. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract. Understanding the transport of objects and material in the marginal ice zone (MIZ) is critical for human operations in polar regions. This can be the transport of pollutants, such as spilled oil, or the transport ...

-
(Research report / Forskningsrapport, 2005)This report provides a discussion about the fundamentals of the frequentist approach to the classical nonlinear least squares head - discharge power-law rating curve model, which is a vital procedure in practical hydrology. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Marine biofouling on a ship's hull and propeller increases the resistance of the ship moving through water and reduces the propulsion efficiency of the ship. Estimating the effect of fouling is difficult, as the biomass ...
-
(Master thesis / Masteroppgave, 2015)The Aalen-Johansen estimator for calculation of transition probabilities in a multi-state model, builds on the assumption that the data are Markovian. For real data, the Markov property may not be fulfilled, and it is then ...

-
(Research report / Forskningsrapport, 2002)Multi-state models are used to describe situations where individuals may move among a finite number of states defined by specific conditions of health, including death. The transition intensities of the models are described ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We calculate the motivic stable homotopy groups of the two-complete sphere spectrum after inverting multiplication by the Hopf map η over fields of cohomological dimension at most 2 with characteristic different from 2 ...
