| Mar 26, 2011 at 20:00 | comment | added | Ryan Budney | Back in the 70's and 80's there was quite a lot of work on various Steenrod realization problems where you replace singular bordism by bordism of various more degenerate objects -- stratified spaces with various restrictions on the singular strata. $\mathbb Z_k$-manifolds were one popular example. You could turn these kinds objects into cobordism categories. See also Buoncristiano, Rourke and Sanderson's work, etc. | |
