# Supersymmetric Quantum Field Theory: Indefinite Metric

Florin Constantinescu
February 11, 2008
We study the recently introduced Krein structure (indefinite metric) of the $N=1$ supersymmetry and present the way into physical applications outside path integral methods. From the mathematical point of view some perspectives are mentioned at the end of the paper.
