-linear operations in complex cobordism and the -spherical bordism theory
arXiv:2106.11876 · doi:10.4213/im9334
Abstract
We study the -linear operations in complex cobordism and prove that they are generated by the well-known geometric operations . For the theory of -spherical bordism, we describe all -linear multiplications on and projections . We also analyse complex orientations on and the corresponding formal group laws . The relationship between the formal group laws and the coefficient ring of the -theory was studied by Buchstaber in 1972. We extend his results by showing that for any -linear multiplication and orientation on , the coefficients of the corresponding formal group law do not generate the ring , unlike the situation with complex bordism.
