The relation stating that a structure makes a formula or sentence true under a specified variable assignment when one is needed.
openlogic-model-theoryEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
The recursively defined satisfaction relation evaluates terms and formulas in a first-order structure after an interpretation of the nonlogical symbols and, for open formulas, a variable assignment are fixed.
Equip an existing carrier or structured object with additional chosen data, when such compatible data exists. Use a construction junction when several independently meaningful inputs must coexist on the same carrier or interact compatibly.

This is an authored directed relation from the source endpoint to the target endpoint.
Semantic consequence is defined by universal satisfaction: when every structure satisfying all sentences in also satisfies .
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
