Continuous first order logic and local stability
... Yet, continuous first order logic has significant advantages over earlier formalisms for metric structures. To begin with, it is an immediate generalisation of classical first order logic, more natural and less technically involved than previous formalisms. More importantly, it allows us to beat the ab ...

One example is Presburger arithmetic, in which the universe is the natural numbers and there is a single function, plus, whose properties are axiomatized. There ar ...

The substitutional theory of logical consequence

Deep Sequent Systems for Modal Logic

Prominent examples of unlabelled formalisms are the hypersequent calculus [1] and the display calculus [2, 10]. These and more can be found in the survey by Wansing [11]. A ...
