Recursive Prime Factorizations: Dyck Words as Numbers

Ralph L. Childress

I propose a class of numeral systems where numbers are represented by Dyck words, with the systems arising from a generalization of prime factorization. After describing two proper subsets of the Dyck language capable of uniquely representing all natural and rational numbers respectively, I consider "Dyck-complete" languages, in which every member of the Dyck language represents a number. I conclude by suggesting possible research directions.
