Efficient scattering approach to seismic full-waveform inversion in anisotropic elastic media with variable density
Kui Xiang, Morten Jakobsen, Ujjwal Shekhar +2
This paper introduces a novel matrix-free approach for full waveform inversion in anisotropic elastic media, incorporating density variation through the utilization of the distorte…
3D induction log modelling with integral equation method and domain decomposition preconditioning
Durra Handri Saputera, Morten Jakobsen, Koen W. A. van Dongen +3
The deployment of electromagnetic (EM) induction tools while drilling is one of the standard routines for assisting the geosteering decision-making process. The conductivity distri…
Iterative solution of the Lippmann-Schwinger equation in strongly scattering acoustic media by randomized construction of preconditioners
Kjersti Solberg Eikrem, Geir Nævdal, Morten Jakobsen
In this work the Lippmann-Schwinger equation is used to model seismic waves in strongly scattering acoustic media. We consider the Helmholtz equation, which is the scalar wave equa…
Coefficient multipliers of growth spaces of harmonic functions
Kjersti Solberg Eikrem, Eugenia Malinnikova
Let be the space of harmonic functions in the unit ball that are bounded by some increasing radial function with ; these spa…
Random harmonic functions in growth spaces and Bloch-type spaces
Kjersti Solberg Eikrem
Let and be the spaces of harmonic functions in the unit disk and multi-dimensional unit ball which admit a two-sided radial majorant…
Wavelet decomposition of harmonic functions in growth spaces
Kjersti Solberg Eikrem, Eugenia Malinnikova, Pavel A. Mozolyako
Spaces of harmonic functions in upper half-space with controlled growth near the boundary are described in terms of multiresolution approximations. The results are applied to prove…
Hadamard gap series in growth spaces
Kjersti Solberg Eikrem
Let be the class of harmonic functions in the unit disk which admit a two-sided radial majorant . We consider functions that fulfill a doubling condition. W…
Radial growth of harmonic functions in the unit ball
Kjersti Solberg Eikrem, Eugenia Malinnikova
We study harmonic functions which admit a certain majorant in the unit ball in . We prove that when the majorant fulfills a doubling condition, the extremal growth or decay…
