Deep Inference for Hybrid Logic
Lutz Straßburger · 2007
This paper describes work in progress on using deep inference for designing a deductive system for hybrid logic. We will see a cut-free system and prove its soundness and completeness. An immediate observation about the system is that there is no need for additional rewrite rules as in Blackburn’s tableaux, nor substitution rules as in Seligman’s sequent system.
