摘要

We present an approach to the Kervaire-invariant-one problem. The notion of the geometric (Z/2 ⊕ Z/2)-control of self-intersection of a skew-framed immersion and the notion of the (Z/2 ⊕ Z/4)-structure on the self-intersection manifold of a D_4-framed immersion are introduced. It is shown that a skew-framed immersion f:M (3n+q)/4 → R~n, 0 < q n (in the ((3n)/4 + ε)-range), admits a geometric (Z/2 ⊕ Z/2)-control if the characteristic class of the skew-framing of this immersion admits a retraction of order q, i.e., there exists a mapping κ_0: M ~((3n+q)/4)→ RP ~((3(n-q))/4) such that this composition I o κ_0: M~((3n+q)/4) → RP~((3(n-q))/4) →RP~∞ is the characteristic class of the skew-framing of f. Using the notion of (Z/2 ⊕ Z/2)-control, we prove that for a sufficiently large n, n = 2~1 - 2, an arbitrarily immersed D4-framed manifold admits in the regular cobordism class (modulo odd torsion) an immersion with a (Z/2 ⊕ Z/4)-structure.
