Abstract

In this papers we study a new concept namely (M-approximate cofibration) Mixed Approximate Cofibration and(M-approximate Hurewicz cofibration) Mixed approximate Hurewicz cofibration. Most of theorem which are valid for cofibration will also be valid for (M- cofibration); the others will be valid if we add extra conditions . Among the results we obtain are:
1-A product of two Mixed approximate Cofibration(Mixed approximate Hurewicz cofibration) is also a Mixed approximate Cofibration(Mixed approximate Hurewicz cofibration)
- The M-pullback of Mixed approximate Cofibration(Mixed approximate Hurewicz cofibration)is also Mixed approximate Cofibration(Mixed approximate Hurewicz cofibration
Key words: Mixed approximate (Hurewicz) Cofibration , M-pullback, Lowering homotopy property.
