SUMMARY
The discussion centers on extending a D-cochain to a D-cocycle within the context of a sphere bundle \(\pi: E \rightarrow M\) with the structure group Diff(S^n). The key point is that this extension allows for the derivation of a global form that restricts to a specific d-cohomology class. Understanding this relationship is crucial for grasping the implications of D-cohomology in differential geometry.
