On the basis of Effinger and Hayes’ theorem about the Goldbach 3_primes property of polynomial rings F over finite fields F , by model_theoretic method it is proved that for each characteristic k (including 0), there...
This letter is a continuation of previous work(Scientia Sinica, 27(1984), 1: 16—23). By using number-theoretic and model-theoretic arguments, we establish the existence of Goldbach and nonGoldbach extension rings of ...
This letter is a continuation of a previous paper A class of commutative rings Without Goldbach property, on the basis of which we further obtained the following theorem.
This letter is a continuation of a previous paper 'A class of commutative rings with Goldbach property'. (Its abstract was published in 科学通报,26(1981), 18: 1149; the details will appear in 北京师范大学学报.) Now, we
Model theory is usually regarded as an abstract branch of mathematical logic. The aim of our work is to find some new examples of application of conclusions on model theory. Considering a certain type of residue class...
