Description

In the past few months, Brown and Smolka published three papers about specific fragments of higher order logic and presented corresponding tableau systems which are complete, cut-free and in one case terminating. I am planning to extend these tableau systems to include rules for an if-then-else operator, a description operator and a choice operator while preserving the existing properties of the systems. I will give rules for an if-then-else operator and propose rules for a choice operator. The rules for a choice operator are based on a paper by Mints from 1996.
