Dimensional reduction is reformulated in a mathematically consistent way, and an elegant and general method is presented that allows to study the supersymmetry-invariance of dimensional reduction in an easy manner. This method is applied to several supersymmetry identities at the one- and two-loop level, and thus the extent to which dimensional reduction is known to preserve supersymmetry is significantly enlarged.Talk given at the 2005 International Linear Collider Workshop - Stanford, USA. 6 pages, 1 figureHigh Energy Physics - Phenomenologytext
