Attaching maps in a product of CW-complexes

  1. Apr 29, 2009 #1
    Could someone please explain to me how to find the differential operators in a product of CW complexes, if the individual differential operators are known?

    For example, I know that RP2x S2 has 1 0-cell, 1 1-cell, 1 2- cells and 1 4-cell, and I know how the cells of RP2 and S2 are attached, but I don't know how the cells of RP2 x S2 are attached.

    I'd be happy with a link to somewhere that explains this, I haven't been able to find a source. Thanks.

    Thanks...I should have known it would be somewhere in Hatcher.
