Inverse Semigroups of Metrics on Doubles Related to Certain Subsets

computable. As a special case, we study this subsemigroup related to the family of geodesic rays starting from the basepoint, for Euclidean spaces and for trees. [2/2 of https://t.co/icomsrfYsS]

Recently we have shown that the equivalence classes of metrics on the double of a metric space $X$ form an inverse semigroup. Here we define an inverse subsemigroup related to a family of isometric subspaces of $X$, which is more [1/2 of https://t.co/icoms
