The Group Of Self-homotopy Equivalences Of Wedge Spaces

The group of self-homotopy equivalences Aut(X V Y) is represented as a product of two subgroupsAutx(X\/Y)and Auty(XVY) under the assumption that the self-equivalences of X V Y can be diagonalized. Moreover , an analogous result holds for the special subgroup Aut*(X V Y) of Aut(X V Y).
