# Cohomology and massless fields

@article{Eastwood1981CohomologyAM, title={Cohomology and massless fields}, author={Michael Eastwood and Roger Penrose and Raymond O. Wells}, journal={Communications in Mathematical Physics}, year={1981}, volume={78}, pages={305-351} }

The geometry of twistors was first introduced in Penrose [28]. Since that time it has played a significant role in solutions of various problems in mathemetical physics of both a linear and nonlinear nature (cf. Penrose [29], Penrose [35], Ward [48], and Atiyah-Hitchin-Drinfeld-Manin [2], see Wells [52] for a recent survey of the topic with a more extensive bibliography). The major role it has played has been in setting up a general correspondence which translates certain important physical…
