摘要: Explicit differential and integral relationsthat afford a natural basis for systematicallyevaluating twistor diagrams are presented. Theevaluation techniques include making use of aconformally invariant parametrization prescription along with setof graphical computational devices which clearly bringout the striking features integrals associatedwith such diagrams. It appears that main results relevant calculations carried outearlier can all be extracted from structures ariseout effectively implementing techniques. Both thetopological character location contours presumably borne by any turn out to bespecified in unique way. Another explanation thebreaking conformal symmetry arises thecontext theory is automaticallyprovided.
