Reversible maps and composites of involutions in groups of piecewise linear homeomorphisms of the real line
Nick Gill, Ian Short
An element of a group is \emph{reversible} if it is conjugate to its own inverse, and it is \emph{strongly reversible} if it is conjugate to its inverse by an involution. A group e…
