Malliteoreettinen
Malliteoreettinen is a Finnish term that translates to "model-theoretic" in English. It refers to a branch of mathematical logic and philosophy that uses the concept of mathematical models to study the properties of formal theories. A model of a theory is an interpretation of its symbols and formulas in a mathematical structure, such as a set with relations and functions. If all the sentences of a theory are true in a particular interpretation, then that interpretation is a model of the theory.
Model theory investigates the relationship between formal languages, their theories, and the structures that satisfy them.
The development of model theory has had significant impacts on various fields of mathematics, including algebra,
