Query: A formalism for the calculus of variations with spinors   We develop a frame and dyad gauge-independent formalism for the calculus of
variations of functionals involving spinorial objects. As part of this
formalism we define a modified variation operator which absorbs frame and spin
dyad gauge terms. This formalism is applicable to both the standard spacetime
(i.e. SL(2,C)) 2-spinors as well as to space (i.e. SU(2,C)) 2-spinors. We
compute expressions for the variations of the connection and the curvature
spinors.
