The Browder-Livesay Invariants,We say that an involution (. .) of a homotopy sphere . . . if there is an embedded (smoothly or p.1., depending on the category we’re working on) homotopy sphere . . ? . . which is invariant under .. We also say that (. .) is a . of (.|., . ) and that (.|. ., . . ) is a . of (. .). See also IV.3.2 and V.1.

Gleason-score

Combinatorial Classification of Involutions,We consider in this section the maps.which are, respectively, the double covering, the natural inclusion and the map of degree 1 (pinching the complement of an open ball to a point). . is the cofibre (mapping cone) of ., .is the cofibre of ., and the composition . . has degree 0 if . is even, degree 2 if . is odd.
