Topology,or example, we will show in Section 5.4 that .(.) and .(.) have the same Betti numbers if and only if . and . are .-equivalent, and that .(.) and .(.) have isomorphic cohomology rings if and only if . and . are .—equivalent.

Anticholinesterases and War Gases, the groups. The columns index the types . of the orbits. This information is sufficient to construct the matrix .(.) in each case. For example, Table C.2 shows that in .. there are two orbits .., .. of type .. with cardinalities 12, 6 and one orbit of type .(3) with cardinality 8. The matrix .(..)

Algebras,n Section 3.1. This construction is generalized to affine arrangements in Section 3.2. The algebra .(.) is the quotient of the exterior algebra .(.) based on . by a homogeneous ideal .(.), .(.) = .(.) / .(.). This algebra is constructed using only .(.). It will reappear in Chapter 5 with a topologic
