Involutions on Spin 4-manifolds
We show that a simply-connected spin 4-manifold which admits a locally linear involution must have vanishing signature. We also show that the codimensions of all components of the fixed point set of an involution on a spin 4-manifold are the same modulo 4 . There is no assumption of local linearity in this result, which extends a lemma of Atiyah and Bott. This note records two results about inv...
متن کاملSurgery and involutions on 4-manifolds
We prove that the canonical 4-dimensional surgery problems can be solved after passing to a double cover. This contrasts the longstanding conjecture about the validity of the topological surgery theorem for arbitrary fundamental groups (without passing to a cover). As a corollary, the surgery conjecture is reformulated in terms of the existence of free involutions on a certain class of 4-manifo...
متن کاملOn Geometry of Linear Involutions
Let V be an n-dimensional left vector space over a division ring R and n ≥ 3. Denote by Gk the Grassmann space of k-dimensional subspaces of V and put Gk for the set of all pairs (S, U) ∈ Gk ×Gn−k such that S+U = V . We study bijective transformations of Gk preserving the class of base subsets and show that these mappings are induced by semilinear isomorphisms of V to itself or to the dual spac...
متن کاملFree Piecewise Linear Involutions on Spheres
If T is a piecewise linear fixed-point free involution on S, the orbit space Q = S/T is a PL-manifold homotopy equivalent to P»(JR) ~ P n [2J; the affirmative solution to the Poincaré conjecture implies that conversely for n&Z, 4 the double covering manifold of any such Q can be identified with S. Write In for the set of (oriented if n is even) PL-homeomorphism classes of manifolds Q homotopy e...
متن کاملReturn words of linear involutions and fundamental groups
We investigate the natural codings of linear involutions. We deduce from the geometric representation of linear involutions as Poincaré maps of measured foliations a suitable definition of return words which yields that the set of first return words to a given word is a symmetric basis of the free group on the underlying alphabet A. The set of first return words with respect to a subgroup of fi...
