Abstract:The groups $J_{n,k}^{2^k+1}$ of cobordism classes in the unoriented cobordism group $MO_n$ containing a representative $M^n$ admitting a $(Z_2)^k$-action with fixed point set of constant codimension $2^k+1$ are determined.

Keywords:Indecomposable cobordism class   fixed point set   projective space bundle   $(Z_{2})^k$-action
