Phantom Maps and Rational Equivalences

American Journal of Mathematics, 1994
If \(X\) is a CW-complex, recall that a phantom map \(f : X \to Y\) is a map whose restriction to each \(n\)-skeleton \(X_n\) is null homotopic. The authors study the set \(Ph(X,Y)\) of pointed homotopy classes of phantom maps from \(X\) to \(Y\), with some hypotheses on \(X\) and \(Y\): a pointed connected CW-complex \(X\) is called a finite type ...
