K-theory of S7/Q8 and a counterexample to a result of P.M. Akhmet'ev
Abstract
A simple counterexample is presented to a proposition which is used in the arguments given by P. M. Akhmet'ev in his work on the Hopf invariant and Kervaire invariant. The counterexample makes use of the K-theory of the quotient of the 7-sphere by the quaternion group of order 8.
