continuous logic


Continuous logic is a logic whose truth values can take continuous values in [0,1][0,1]. The main variant used in model theory is motivated by the model theory of Banach spaces and similar structures. The truth is interpreted as probability and there is a concept of random predicates.


Continuous logic is introduced in

  • C. W. Henson, J. Iovino, Ultraproducts in analysis in: Analysis and Logic, London Math. Soc. Lecture Note Series 262, Cambridge University Press 2002.

motivated by

  • Chen-Chung Chang, Jerome H. Keisler, Continuous Model Theory, Annals of Mathematics Studies 58, 1966.

A recent version is in

There is a version of abstract elementary classes in the setting of continuous logic, metric abstract elementary classes.
