Lζ-modülleri ve Jon Carlson'ın bir teoremi

In this thesis, we study Lζ -modules, and using some exact sequences involvingLζ -modules, we give an alternative proof to a theorem by Jon Carlson which saysthat any ZG-module is a direct summand of a module which has a filtration bymodules induced from elementary abelian subgroups.Keywords: Lζ -modules, cohomology, projective module, injective module, projec-tive resolutions, elementary abelian p-subgroups, exact sequences.iii
