Abstract: Using a homotopy-theoretical description of a geometric pairing due to Bredon, we show how to rederive Bredon's results on the pairing. Furthermore, we are able to, in some sense, complete these results by combining the homotopy-theoretical approach with Sullivan's determination of the 2-primary Postnikov decomposition of the space G/PL.
