Abstract
The Adams operations {ψk} considered as self-maps of BU have the property that . Id2n on H2n(BU; ℚ). Sullivan in his M.I.T. notes [12] constructed ψk-type self-maps of BU(n) in the case in which k is prime to n!. Later work by Friedlander[5] and Wilkerson[14] gave constructions for all other compact connected Lie groups G, subject to the condition that k be prime to the order of the Weyl group W(G).Keywords
