ИСТИНА

In the first part of the talk I will give a description of the set of SU-linear cohomological operations in complex cobordism and will show that they are generated by known geometrical operations ∂_i. Then I will talk about some properties of c1-spherical bordism theory W, in particular, I will discuss SU-bilinear multiplications on W and projections from complex cobordism onto W. At the end I will talk about complex orientations of W and some particular results on the coefficients of the corresponding formal group laws.
