Abstract
In this paper we introduce a new tool in algebraic topology which is called (analogous terminology of J.H.C. Whitehead in [1] ) . By studying effect of this complex on the spectral sequences , we obtained some results , such as ;1- Any complex is an 2- Let are two cw-complexes , if , then . 3- If is , then . 4- Let be a cw-complex , if is a , then is a , and the converse is not true .
