【 摘 要 】

In this note we show that there are no higher twistings for the Borel cohomology theory associated to G-equivariant K-theory over a point and for a compact Lie group G. Therefore, twistings over a point for this theory are classified by the group H-1 (BG, Z/2) x H-3 (BG, Z). (C) 2010 Elsevier B.V. All rights reserved.
