Some further properties of BMRS transductions

Abstract

This paper expands on Bhaskar et al. (2020)’s result by investigating further properties of BMRS transductions, their connection to regular functions, and their applications in natural-langauge phonology. It introduces a syntactic operator over length-preserving BMRS transductions that is equivalent to function composition. Using this operator, this paper offers a proof that BMRs transductions without predecessor/successor restrictions describe exactly the regular functions. Additionally, it demonstrates applications of BMRS composition to modeling phonological process interactions.
