1/ Some basic concepts: Pure injective modules, finite matrix subgroups and the structure of a module over its endomorphismring.
2/ Infinite dimensional modules over finite dimensional algebras: Construction of infinite-dimensional indecomposable modules and their role in the parametrization of finite dimensional modules.
3/ Modules over artinian PI-rings: Duality and Transpose for finite length modules, existence of AR-sequences, as example: variations of the Kronecker-algebra, geometry of their representation space. |
