Cobordism classes of fiberings over product of projective spaces

Let RP(k) denotethe k-dimensional real projective space. This article deter mines which cobordism classes are represented by the total space of a fibering with pre scribed base space RP (3) × RP (1), RP (2) × RP (1), RP (2) × RP (1) × RP (1) or RP (3) × RP (2).
