Group Cohomology and Extensions
AuthorBreivik, Markus Nordvoll
The goal of this thesis is to classify all extensions where the kernel has order p^s and the cokernel has order p^t, p is a prime, and 1 ≤ s,t ≤ 2. We determine (up to weak congruence) the different combinations of kernel, cokernel and operators, and for each case, calculate the second cohomology group. By comparing resolutions, we get an explicit correspondence between the second cohomology group and the group of congruence classes of extensions. Using this construction, we determine (up to congruence) the extensions for the different combinations.

Group dynamics in a group‐based, individualized physiotherapy intervention for people with multiple sclerosis: A qualitative study Lahelle, Andreas Falck; Øberg, Gunn Kristin; Normann, Britt (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-27)<i>Objective</i> - Group‐based physiotherapy is a common and beneficial intervention for people with multiple sclerosis (MS). Most group interventions are not individually adapted to each participant's needs. Evidence on how individualization and group elements can be combined in a clinical setting is lacking. The objective of this study is to expand the knowledge base in neurological physiotherapy ...
