Fixed Point Sets of Involutions on the Product of Three Spheres

Abstract

Let G = Z2 act on a finitistic space X having mod 2 cohomology of the product of three spheres S^n x S^m x S^l. In this paper, we have determined the fixed point sets of involutions on X. This generalizes J. C. Su [12] results for involutions on the product of two sphere S^n x S^m.
