Framed cobordism of framed submanifolds


Suppose M_1 and M_2 are framed submanifolds of a differential manifold P. A framed cobordism between M_1 and M_2 in P is a framed submanifold with boundary (N, \partial N) inside P \times I, that provides a cobordism between M_1 \times \{ 0 \} and M_2 \times \{ 1 \}.
