On lambda-rings and topological realization
arXiv:math/0501515 · doi:10.1155/IJMMS/2006/91267
Abstract
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 structures are topologically realizable by the K-theory of torsionfree spaces is also considered for truncated polynomial rings.
