Valuations, bijections, and bases

open access: yes
The aim of this paper is to build a theory of commutative and noncommutative injective valuations of various algebras. The targets of our valuations are (well-)ordered commutative and noncommutative (partial or entire) semigroups including any sub-semigroups of the free monoid $F_n$ on $n$ generators and various quotients. In the case when the (partial)
