Abstract
We prove strong normalization of tq-reduction for all standard versions of sequent calculus for classical and intuitionistic (second and first order) logic and give a perspicuous argument for the completeness of the focusing restriction on sequent derivations.
Research part of the project ‘Geometry & Logic’, financed by the Netherlands Organization for Scientific Research (NWO)
supported by a fellowship of the Consiglio Nazionale delle Ricerche (CNR)
