16:00 Paul Pearson, The mod 2 homology of the spaces in the connective Omega-spectrum of topological modular forms in Auditorium 9.
Abstract: The mod 2 homology of topological modular forms (tmf) is a Hopf ring. Every mod 2 Hopf ring is equivalent to a Dieudonne' ring. We calculate the Dieudonne' ring for the nonnegatively graded spaces in the Omega-spectrum for tmf, and show that it splits into two parts that occasionally overlap. One part comes from the homology of the spectrum tmf, and the other part comes from the homology of QS^k, the kth space in the Omega-spectrum of the sphere.

FRIDAY
