Equivariant analogues of Zuckerman functors

It is shown how analogues of Zuckerman functors ca be constructed in the setting of Beilinson-Ginzburg equivariant derived categories of Harish-Chandra modules. They are given by an explicit formula, which works equally well in the case of modules with a given infinitesimal character. This is important if one wants to apply Beilinson-Bernstein localization. We also show how to recover the usual Zuckerman functors from the equivariant ones by passing to cohomology.
