摘要：

We consider the real topological K-groups of a toric manifold M, which turns out to be closely related to the topology of the small cover M-R, the fixed points under the canonical conjugation on M. Following the work of Bahri and Bendersky (2000), we give an explicit formula for the KO -groups of toric manifolds, and then we characterize the two extreme classes of toric manifolds according to their mod 2 cohomology groups as A(1)-modules.
