On vanishing of all fourfold products of the Ray classes in symplectic cobordism
arXiv:1909.07211 · doi:10.1090/proc/15058
Abstract
This note provides certain computations with transfer associated with projective bundles of Spin vector bundles. One aspect is to revise the proof of the main result of \cite{B} which says that all fourfold products of the Ray classes are zero in symplectic cobordism.
