Phantom elements and its applications
Jianzhong Pan, Moo Ha Woo · Contemporary mathematics - American Mathematical Society · 2001
In our previous workfll], a relation between Tsukiyama problem about self homotopy equivalence was found by using a generalization of phantom map. In this note , fundamental result is established for such a generalization. This is the first time one can deal with phantom maps to space not satisfying finite type condition. Application to Forgetful map is also discussed briefly.
