Unstable K -cohomology algebra is filtered λ -ring

International Journal of Mathematics and Mathematical Sciences, 2003, vol. 2003, 1-13

Abstract:

Boardman, Johnson, and Wilson (1995) gave a precise formulation for an unstable algebra over a generalized cohomology theory. Modifying their definition slightly in the case of complex K -theory by taking into account its periodicity, we prove that an unstable algebra for complex K -theory is precisely a filtered λ -ring, and vice versa.
