The order of the group of self-homotopy equivalence of wedge spaces
Abstract
In this paper Aut( X Y)\# the order of the group of self-homotopy equivalence of wedge spaces is studied. Under the condition of reducibility, we decompose Aut(t=1kXt) to the product of subgroups which generalizes the known results for k=2. Then we also give the formula for Aut(t=1k Xt)\#.
