Abstract:

Say that a commutative ring spectrum is even if its homotopy groups are trivial in odd degrees. We can approximate an arbitrary ring R by taking the limit, over all maps R--->A with A even, of A. Moreover, we can filter R by declaring fil^n(R) to be the limit, over all maps R--->A with A even, of the (2n-1)-connected cover of A. I will discuss how to compute fil^*(R) for various commutative ring spectra R. This is joint work with Arpon Raksit and Dylan Wilson.
