Oriented bordism

Witrynawhere a is again the bordism product and ß has degree —1. As an example, we apply Theorem A with X = B(Zp), for p an odd prime. The oriented bordism spectral sequence of B(Zp) collapses [3, (34.1)], and of course B(Zp) satisfies the standing finiteness condition and condition (b) of Theorem A. WitrynaIt is supposed to play the same role for -bordism as -theory does for -bordism. Its …

WitrynaTHE ORIENTED COBORDISM RING. Araminta Gwynne. Published 2016. Mathematics. We give an exposition of the computation of the oriented cobordism ring ΩSO ∗ using the Adam’s spectral sequence. Our proof follows Pengelley [15]. The unoriented and complex cobordism rings are also computed in a similar fashion. math.uchicago.edu. WitrynaDefine the n-th singular bordism group ⌦n(X) by the oriented bordism classes of maps f : M ! X with a closed oriented manifold as source. Addition comes from the disjoint union, the neutral element is represented by the map ;!X, and the inverse is given by changing the orientation. It becomes a covariant functor by composing the …

WitrynaIn the bordism theory 0* (Zk) of smooth, orientation-preserving Z2-actions all torsion has order two. Furthermore, the torsion classes inject in the unoriented theory N* (Z2k), and any class represented by a stationarypoint free action has infinite order. In addition, a procedure is given for producing Smith constructions in some generality.
