Title: Harmonic spinors from twistors and potential forms,
Abstract: Symmetry operators of twistor spinors and harmonic spinors can be constructed
from conformal Killing-Yano forms. Transformation operators relating twistors
to harmonic spinors are found in terms of potential forms. These constructions
are generalized to gauged twistor spinors and gauged harmonic spinors. The
operators that transform gauged twistor spinors to gauged harmonic spinors are
found. Symmetry operators of gauged harmonic spinors in terms of conformal
Killing-Yano forms are obtained. Algebraic conditions to obtain solutions of
the Seiberg-Witten equations are discussed.
