| Abstract | ||
| In this work we introduce and study a new notion in algebraic topology , which we call " a new exact sequence " which is a generalization of " a certain exact sequence " of J.H.C.Whitehead . Consider the following sequence : denote The sequence defined in a natural manner , Where we call " a new exact sequence " which is denoted by NES . We obtain some results from NES , which are ; The our NES it is really exact , the class of all NES,s and the homomorphisms between these sequences forms a category . | ||
