摘要 Special generators of the unoriented cobordism ring MO* are constructed to determine the groups J<sub>n,k</sub><sup>τ</sup> of n-dimensional cobordism classes in MO<sub>n</sub> containing a representative M<sup>n</sup> admitting a (Z<sub>2</sub>)<sup>k</sup> -action with fixed point set of constant codimension.
