摘要

Boardman, Johnson, and Wilson(1995)在广义上同调理论上给出了一个不稳定代数的精确公式。考虑到复K理论的周期性，我们稍微修改了它们的定义，证明了复K理论的不稳定代数是一个过滤的λ环，反之亦然。

Unstable K-cohomology algebra is filtered λ-ring

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.
