## Note on the Homotopy Type of Mapping Cones" PETER HILTON I n [2] and [3] we proved certain theorems about the semi-group of homotopy types of based spaces where the composition operation is just the disjoint union with identification of base points. These results were suggested by certain obse
For any poset P let J(P) denote the complete lattice of order ideals in P. J(P) is a contravariant functor in P. Any order-reversing map f: P-+Q can be regarded as an isotone (= order-preserving) map of either P\* into Q or P into Q\*. The induced map of J(Q) to J(P\*) (resp. J(Q\*) into J(P)) will
