SU–кобордизмы и формальные группы

Математический сборник. 1972. Т. 88. № 4. С. 536-545.

In this paper a six-valued two-dimensional formal group with ring of coefficients Λ2, lying in ΩU[1/2], is constructed. It is proved that the ring Λ2[1/2] coincides with the image of the ring ΩSU[1/2] in the ring ΩU[1/2].
