(Master thesis / Masteroppgave, 2013)Mathematics in climate research is rarely mentioned in the everyday conversations or in the media when talking about climate changes. This thesis therefore focus on the central role mathematics plays in climate research, ...

(Master thesis / Masteroppgave, 2023)Grassmannians are varieties parameterizing the k-dimensional subspaces of an n-dimensional vector space. To a point in a Grassmannian we associate two objects: A representable matroid storing combinatorial data about linear ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)With modern high-dimensional data, complex statistical models are necessary, requiring computationally feasible inference schemes. We introduce Max-and-Smooth, an approximate Bayesian inference scheme for a flexible class ...
-
(Research report / Forskningsrapport, 2006)We study scalar conservation laws in one dimension with the flux function being discontinuous in the space variable. The existence and stability of infinitely many entropy solutions is shown. The existence is a consequence ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)By record linkage one joins records residing in separate files which are believed to be related to the same entity. In this paper we approach record linkage as a classification problem, and adapt the maximum entropy ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)We prove a maximum principle of optimal control of stochastic delay equations on infinite horizon. We establish first and second sufficient stochastic maximum principles as well as necessary conditions for that problem. ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Time change is a powerful technique for generating noises and providing flexible models. In the framework of time changed Brownian and Poisson random measures we study the existence and uniqueness of a solution to a general ...

(Research report / Forskningsrapport, 2003)We formulate and prove a non-local ``maximum principle for semicontinuous functions'' in the setting of fully nonlinear degenerate elliptic integro-partial differential equations with integro operators of second order. ...
-
(Research report / Forskningsrapport, 2006)We study the problem of optimal control of a jump diffusion, i.e. a process which is the solution of a stochastic differential equation driven by Lévy processes. It is required that the control process is adapted to a given ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)In this paper, we initiate a study on optimal control problem for stochastic differential games under generalized expectation via backward stochastic differential equations and partial information. We first prove a sufficient ...
