Generalizations of the kervaire invariant

Webthe appearance of an analogue to the Kervaire invariant [7: ? 8]. An interesting by-product of this investigation will be the fact that these invariants seem to detect the differentiable structure on the knot in half the cases (i.e.; knots in (4q - 1)-space. See ? 3.2 and 3.3), but ignore it in the other half ((4q + 1)-space). WebWe will consider its generalization to more general spacetime dimensions and to more general spacetime structures, and show that this action is projective up to a multiplication by an invertible topological phase, whose partition …

WebThis is the definitive account of the resolution of the Kervaire invariant problem, a major milestone in algebraic topology. It develops all the machinery that is needed for the proof, and details many explicit constructions and computations performed along the way, making it suitable for graduate students as well as experts in homotopy theory. ... The Kervaire invariant is a generalization of the Arf invariant of a framed surface (that is, a 2-dimensional manifold with stably trivialized tangent bundle) which was used by Lev Pontryagin in 1950 to compute the homotopy group of maps (for ), which is the cobordism group of surfaces embedded in with trivialized normal bundle.
