,The Structure of Promislow’s Continuous Free Product,ons of the form .: → ℝ with at most a finite number of discontinuities, where . ∈ ℝ is a non-negative real number. The multiplication in . is reminiscent of the path multiplication used to construct the fundamental group of a topological space.

Foldings of ,-trees,this mimics the author’s topological proof, but some new consequences are drawn. Theorems of Shenitzer and Swarup on amalgamations and HNN-extensions over cyclic subgroups are deduced as a consequence and somewhat generalized.
