The discriminator subvarietyeducible algebras in . with type . monolith, and that . is the variety generated by .. This chapter is devoted to a proof of the theorem below, which is one of the two principal results in Part I. A good portion of the proof of this theorem has already been given in Chapter 3.

CREEK

The Abelian subvariety call transfer principles. Using a theorem concerning these principles which will be proved in the next chapter, we give a short proof that . V . is an Abelian variety. The concept which we now introduce, and our reasoning about it, depend heavily on tame congruence theory. (See § 0.6.)

FILLY

Strongly solvable varietiesnd . are the sub varieties of V that are defined in Definition 1.1. The first principal result of Part II is achieved in Theorem 9.6: . is strongly Abelian and . is affine. The second principal result is Theorem 11.9: . is equivalent to a structured variety of multi-sorted unary algebras. The third

More transfer principles on how these labels may be distributed, depending on the shape of ., but without added assumptions there is much freedom. If .(.) happens to be decidable (structured), then we will show that . must satisfy the (.) and the (.) transfer principles as defined in Chapter 5.

Three interpretations of these lemmas, we will construct an interpretation of the class of all graphs into .(.). These constructions were inspired indirectly by A. P. Zamyatin [1978a], through the work of Burris and McKenzie [1981]. We will first restate Lemma 8.4 and then proceed to prove it.

The unary caseat for such varieties, the properties of being undecidable, hereditarily undecidable, unstructured, or ω-unstructured, all coincide. The results of Chapter 11 reduce the problem to determining those locally finite, essentially unary, .-sorted varieties (for . ≥ 1) which are decidable. For the purpos
