摘要：

Let G = Z(2) act freely on a finitistic space X with mod 2 cohomology ring isomorphic to the product of a real projective space and 2-sphere S2. In this paper, we determine the Conner and Floyd's mod 2 cohomology index and the Volovikov's numerical index of X. Using these indices, we discuss the nonexistence of equivariant maps XSn and SnX. The covering dimensions of the coincidence sets of continuous maps X (k) are also determined.
