In time, theorists used this and other evidence to develop the "standard model" theory.
In so doing, they helped found what are now known as metamathematics and model theory.
Much of work during that time was on first order logic and model theory.
He continues to research into permutation groups and model theory.
They are sometimes called stable groups, though this term normally means something quite different in model theory.
When this 780-page book appeared in 1993, it quickly became one of the standard textbooks on model theory.
This work was seminal to the area of finite model theory.
These classes are a main subject of study in model theory.
In the context of model theory, however, this proof is somewhat more difficult.
Many important properties in model theory can be expressed with types.
