The SageManifolds project is being built upon the huge amount of work by SageMath developers and benefits from discussions with the entire SageMath community.

The following persons have directly contributed to SageManifolds:

Besides, before the SageManifolds project, Joris Vankerschaver introduced in SageMath the class DifferentialForm to deal with differential forms on a fixed coordinate patch. This class inspired the storage of tensor components as Python dictionaries (see ticket #24444 for details).
