Canonical deformations of De Rham complexes Academic Article uri icon


  • This type of deformation was investigated in [AST: Sul; Re]. It was shown that there is a corresponding flat deformation ((M,,,) of the ring ((M,) of functions on nxn matrices.((M,,,) is a bialgebra coacting on A,, and 2 ek* is an extra deformation parameter. The bialgebra ((M,,,) actually coacts on the deformed de Rham complex 42:,–(2*(A:,)–4", 42,. This is the differential graded algebra (DGA)
