Commutatively deformed general relativity: foundations, cosmology, and experimental tests
Abstract An integral kernel representation for the commutative $$\star $$ ⋆ -product on curved classical spacetime is introduced. Its convergence conditions and relationship to a Drin’feld differential twist are established. A $$\star $$ ⋆ -Einstein field equation can be obtained, provided the matte...
