| Abstract:In this papers we study a new concept namely Mixed cofibration (M- cofibration) and Mixed Hurewicz cofibration (M- Hurewicz cofibration).Most of theorem which are valid for cofibrationwill bealso valid for (M- cofibration) the others will be valid if we add extra condition . Among the result we obtain are: 1-A product of two Mixed Cofibration(Mixed Hurewicz cofibration) is also a Mixed Cofibration(Mixed Hurewicz cofibration)2- The M-pullback of Mixed Cofibration(Mixed Hurewicz cofibration)is also Mixed Cofibration(Mixed Hurewicz cofibration) | ||
