Method of the rheostat for studying properties of fragments of theoretical sets
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 In this article discusses the model-theoretical properties of fragments of theoretical sets and the rheostat method. These two concepts: theoretical set and rheostat are new. The study of this topic in the framework of the study of Jonsson theories, the
