Forcing companions of Jonsson AP-theories
Қарағанды университетінің хабаршысы. Математика сериясы, 2022 This article is devoted to the study of the forcing companions of the Jonsson AP-theories in the enriched signature. It is proved that the forcing companion of the theory does not change when expanding the theories under consideration, which have some ...

The property of independence for Jonsson sets
Қарағанды университетінің хабаршысы. Математика сериясы, 2016 The studies carried out in this article are connected with the description of model - theoretic properties of some, generally speaking, incomplete classes of theories that make a subclass of inductive theories.

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric
