Weyl`s Predicative Classical Mathematics as a Logic
... very well suited for formalising intuitionistic mathematics. There are several ways in which a type theory may be modified so as to be appropriate for formalising classical mathematics. This cannot however be done without changing the structure of the datatypes, because the two interact so strongly. ...

... (and with ‘reasonable’ use of other resources such as memory). Certain classes of logical problem are not only intractable but also undecidable. This means that there is no program that, given any instance of the problem, will in finite time either: a) find a solution; or b) terminate having determi ...

Propositional Discourse Logic
... illustrates well this modal element. In the absence of any additional information, there seems to be no reason to choose between d and e, and keeping both possibilities is the most natural, not to say ethical, way. Under special circumstances, such sets of possibilities can be narrowed to unique tru ...
