Abstract

The Kervaire Invariant 1 Problem until recently was an open problem in algebraic topology. Hill-Hopkins-Ravenel theorem clams a negative solution of the problem for all dimensions n=2l-2, l ≥ 8. We prove the statement of Hill-Hopkins-Ravenel theorem for all dimensions 2l-2, l ≥ l0, where l0 is a sufficiently great positive integer. The proof is based on the Hirsh control principle and the Compression theorem by the author. A notion internal symmetry: of Abelian (for skew-framed immersions), bi-cyclic (for ℤ/2[3]-framed immersions) and quaternion-cyclic structure (for ℤ/2[4]-framed immersions) are introduced.
