Streszczenie
We calculate the mapping H^*(BO;{\mathbb Z}_2) \rightarrow H^*(K^{1,0};{\mathbb Z}_2) and obtain a generating system of its kernel. As a corollary, bounds on the codimension of fold maps from real projective spaces to Euclidean space are calculated and the rank of a singular bordism group is determined.
