Discussing “Nested Sequents for Intuitionistic Logics”
About a year and a half ago I wrote about hypersequents, a modification of the tried and trusted sequent calculus approach to structural proof theory. In that setting, instead of working with a single sequent (a set of premises alongside a set of possible conclusions) we work with a list of sequents. In this paper,…

Discussing “Combining Classical and Intuitionistic Logic”
This short but fun little paper discusses how we can combine two different logics – classical and intuitionistic – into one. Classical logic is the logic of Boole where every proposition has a definite value of True or False and negation simply inverts the value, so that ‘p or not p’ holds for any proposition…
