Prime models of theories of computable linear orderings [PDF]

open access: yesProceedings of the American Mathematical Society, 2001
We answer a long-standing question of Rosenstein by exhibiting a complete theory of linear orderings with both a computable model and a prime model, but no computable prime model. The proof uses the relativized version of the concept of limitwise monotonic function.

Algebraic Theories of AUNU Permutation Using Group Action with Non- Prime Order

open access: yesInternational Journal of Science for Global Sustainability, 2023
Permutation groups have played important roles in method of enumerating combinatorial objects in recent times. However, the study of the applicability AUNU permutation groups using group action is challenging. In this paper, a new method of constructing group action using the subsequences of (123)- avoiding of AUNU Permutation patterns is provided. The

Invariants for the modular cyclic group of prime order via classical invariant theory

open access: yesJournal of the European Mathematical Society, 2013
Let \mathbb F be any field of characteristic p . It is well-known that there are exactly p inequivalent indecomposable representations V_1,V_2,\dots,V_p

An algorithm for computing theory prime implicates in first order logic

International Journal of Information and Communication Technology, 2007
An algorithm based on consensus method to compute the set of prime implicates of a quantifier free first order formula X was presented in an earlier work. In this paper the notion of prime implicates is extended to theory prime implicates in the first order case.

The theory of integer multiplication with order restricted to primes is decidable

Journal of Symbolic Logic, 1997
AbstractWe show here that the first order theory of the positive integers equipped with multiplication remains decidable when one adds to the language the usual order restricted to the prime numbers. We see moreover that the complexity of the latter theory is a tower of exponentials, of height O(n).

Uniqueness and characterization of prime models over sets for totally transcendental first-order theories

Journal of Symbolic Logic, 1972
If T is a complete first-order totally transcendental theory then over every T-structure A there is a prime model unique up to isomorphism over A. Moreover M is a prime model over A iff: (1) every finite sequence from M realizes an isolated type over A, and (2) there is no uncountable indiscernible set over A in M.The existence of prime models was ...
