1.1 BY THE k-th configuration space of a manifold M we understand the space C”(M) of subsets of M with catdinality k. If c’(M) denotes the space of k-tuples of distinct points in M, ie Ck (M)={(z,,..., zk) eMklzi# zj for i# j>, then C’(M) is the orbit space of C’(M) under the permutation action of the symmetric group Ik, c’(M)-+ c’(M)/E,= Ck (M).Configuration spaces appear in various contexts such as algebraic geometry, knot theory, differential topology or homotopy theory. Although intensively studied their homology is unknown except for special cases, see for example [1, 2, 7, 8, 9, 12, 13, 14, 18, 261 where different terminology and notation is used.
