Abstract
We describe how the usual supercharges of extended supersymmetry may be {\it twisted} to produce a BRST-like supercharge . The usual supersymmetry algebra is then replaced by a twisted algebra and the action of the twisted theory is shown to be generically -exact. In flat space the twisting procedure can be regarded as a change of variables carrying no physical significance. However, the twisted theories can often be transferred to the lattice while preserving the twisted supersymmetry. As an example we construct a lattice version of the two-dimensional supersymmetric sigma model.
