| Abstract: | Special generators of the unoriented cobordism ring MO. are constructed to determine the groups J of n-dimensional cobordism classes in MOn containing a representative Mn admitting a (Z2 )k -action with fixed point set of constant codimension. |
| Keywords: | Cobordism class Fixed point set Projective space bundle. (Z2 )k -action |
