The BRST transformation has been generalised by making the parameter finite and field dependent. Such a transformation is nilpotent and symmetry of the effective actions . However being finite in nature such transformation does not leave path integral measure invariant. The non-trivial Jacobian are made local functional of fields and hence it is possible to relate the generating functionals of different effective theories through finite field dependent BRST transformation. I will discuss construction, extensions and some applications of such generalised BRST transformation in this talk.
