• Geometric rough paths on infinite dimensional spaces 

  Grong, Erlend; Nilssen, Torstein; Schmeding, Alexander (Journal article; Peer reviewed, 2022)

  Similar to ordinary differential equations, rough paths and rough differential equations can be formulated in a Banach space setting. For α ∈ (1/3,1/2), we give criteria for when we can approximate Banach space-valued ...

• Development of robust and efficient solution strategies for coupled problems 

  Storvik, Erlend (Doctoral thesis, 2022-10-10)

  Det er mange modeller i moderne vitenskap hvor sammenkoblingen mellom forskjellige fysiske prosesser er svært viktig. Disse finner man for eksempel i forbindelse med lagring av karbondioksid i undervannsreservoarer, flyt ...

• Evaluating the suitability of close-kin mark-recapture as a demographic modelling tool for a critically endangered elasmobranch population 

  Delaval, Aurelien Nicolas; Bendall, Victoria; Hetherington, Stuart; Skaug, Hans Julius; Frost, Michelle; Jones, Catherine; Noble, Leslie Robert (Journal article; Peer reviewed, 2022)

  Estimating the demographic parameters of contemporary populations is essential to the success of elasmobranch conservation programmes, and to understanding their recent evolutionary history. For benthic elasmobranchs such ...

• A gentle tutorial on accelerated parameter and confidence interval estimation for hidden Markov models using Template Model Builder 

  Bacri, Timothee Raphael Ferdinand; Berentsen, Geir Drage; Bulla, Jan; Hølleland, Sondre Nedreås (Journal article; Peer reviewed, 2022)

  A very common way to estimate the parameters of a hidden Markov model (HMM) is the relatively straightforward computation of maximum likelihood (ML) estimates. For this task, most users rely on user-friendly implementation ...

• Modeling the Process of Speciation Using a Multiscale Framework Including A Posteriori Error Estimates 

  Brun, Mats Kirkesæther; Ahmed, Elyes; Nordbotten, Jan Martin; Stenseth, Nils Christian (Journal article; Peer reviewed, 2022)

• A horizontal Chern–Gauss–Bonnet formula on totally geodesic foliations 

  Baudoin, Fabrice; Grong, Erlend; Vega-Molino, Gianmarco (Journal article; Peer reviewed, 2022)

  Under suitable conditions, we show that the Euler characteristic of a foliated Riemannian manifold can be computed only from curvature invariants which are transverse to the leaves. Our proof uses the hypoelliptic sub-Laplacian ...
