Abstract: Ext-strongly Ding projective dimensions are introduced, some equivalent characterizations of Ext-strongly Ding projective dimensions are presented, this type of module is stable relative to modules with finite projective dimensions and to Ext-strongly Ding projective modules are further investigated.

Key words: Ext-strongly Ding projective modules, Ext-strongly Ding projective dimensions, stability
