Abstract
In this work, we explore properties of totally ordered commutative monoids---we call them tomonoids. We build on the work in [E]. Our goal is to obtain results that will be useful for studying totally ordered rings with nilpotents. Chapter 1 presents background information. In Chapter 2, we present some criteria for determining when a tomonoid is a quotient of a totally ordered free monoid by a convex congruence. In Chapter 3, we show that every positive tomonoid of rank 2 is a convex Rees quotient of a subtomonoid of a totally ordered abelian group. In Chapter 4, we provide a classification of all positive nil tomonoids with 6, 7, and 8 elements. From the classification, we deduce that (1) every positive nil tomonoid with 8 or fewer elements is a quotient of a totally ordered free monoid by a convex congruence (2) any positive nil tomonoid with 8 or fewer elements that satisfies a certain weak cancellation law is a convex Rees quotient of a subtomonoid of a totally ordered abelian group. Finally, in Chapter 5 we note some of the known results relating tomonoids and totally ordered rings, and we suggest further research questions.
