On lambda-rings and topological realization
Donald Yau
It is shown that most possibly truncated power series rings admit uncountably many filtered lambda-ring structures. The question of how many of these filtered lambda-ring structure…

Loop structures on the homotopy type of S^3 revisited
Donald Yau
We observe that the Rector invariants classifying the genus of BS^3 show up in (orthogonal and unitary) K-theory. We then use this knowledge to show purely algebraically how the K-…

Cohomology of lambda-rings
Donald Yau
A cohomology theory for lambda-rings is developed. This is then applied to study deformations of lambda-rings.
