Strong Completeness for Iteration
... T X. We formalise such constructs using natural operations on functors. We also note that PDL and GL are usually interpreted over so-called standard models, in which the program/game constructs have a certain intended meaning. In our general framework this leads to the notion of a standard model rel ...

But the inference also fulfils condition (ii), because its premises are true: all whales are in fact mammals, and all mammals have spinal chords. N ...

... Furthermore, Garfield and Priest (2002) suggest such an interpretation is supported by the fact that Nāgārjuna never explicitly endorses a contradiction at the level of conventional reality. Second, as we have already noted, Nāgārjuna takes reductio arguments to be decisive against his opponents. As ...

Weyl`s Predicative Classical Mathematics as a Logic
... 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. In MLTT, they are one and the same; in ECC or CIC, the unive ...
