Abstract: The notions of Ding gr-injective and Ding gr-flat modules are introduced, and the relations between Ding gr-injective modules and Ding injective modules as well as the relations between Ding gr-injective modules and Ding gr-flat modules are investigated.

Key words: Ding gr-injective modules, Ding injective modules, Ding gr-flat modules
